The Logitech VX Nano Laser Mouse is a very good product that fills a big need for mice: a powerful and convenient wireless mouse for mobile use. You can use this mouse for your desktop, but it's really ideal for your laptop on the go. Sure you can take any mouse with your laptop, but the short receiver, small size and included travel case make this mouse extra portable.

Over the past year of using this mouse, I have come to further appreciate its good features as well as become more aware of its short-comings. This is still one of the better laptop mice you can get, but the size means it will be more ideal for women and smaller children than for men. After using it for hours at a time, I have found that even though I have small hands for a man it's just not as comfortable as some of the larger models.

PROS:
+ The tiny receiver works great! Leave it in your USB port or store it in your mouse!
+ Great optical mouse lets you use it anywhere; no mouse-pads!
+ The side grips have a nice dimpled texture for moving your mouse in comfort
+ The included buttons (L-click, R-click, forward, back, slow) are just enough for most users
+ The buttons can be reprogrammed, though only the *slow* button behind the scroll is worth possibly changing
+ The LED light on top alerts you to a weak battery and when turned on or off
+ The premium scroll wheel switches from normal to turbo with a quick press; can be used to "click" or "hyper-scroll" for normal to superfast scrolling
+ Nice convenient storage compartment for USB receiver inside the mouse
+ Convenient On / Off button for conserving battery power when not in use
+ The AAA batteries are convenient and will last a few months between replacements
+ Great comfort for those with small hands, like women and teens
+ The mouse works for right and left handers; lefties need to click the forward / back buttons with their ring finger or pinkie

CONS:
- The size of the mouse will be too small for extended use by those with medium sized or larger hands, including most men; might be OK for short stints, but over time it becomes tiresome
- The forward / back buttons are placed in a strange location on the top but still off to the side; this actually is more comfortable with the left hand than the right hand
- Logitech's Setpoint software is often the source of complaints, though it has improved with updates over the past year
- The lack of extra function keys limits this mouse from power users
- The list price is in the ball-park, but not a great value

INSTALLATION AND SET UP

This mouse generally works upon plugging it in. The software that comes with it allows you to customize the buttons, but for this mouse I didn't have a need to do that. Only the center button behind the scroll wheel is worth customizing. By default it's set to *slow scroll* mode where you move your mouse to control the direction and speed of scrolling. The rest of the buttons are standard and probably don't need to be changed.

FEATURES

This mouse is sleek and fits nicely in your hand. It's got all the standard buttons, and the scroll button is head over heels above all others. The extra *forward* and *back* buttons are now basically standard requirements.

The VX Nano uses 2 AAA batteries, which means no you can use regular or rechargeable batteries and can replace them when they fail. I burned through my first set after about 3 months of usage. I have found since then that I sometimes need to change batteries every month. Sometimes I can get about 2 months out of a set with light usage.

Even when your batteries are dying, you can squeeze out some more time by switching the batteries or turning the mouse off and on again. Turn it off when it's not in use to preserve power. The power button is on the underside of the unit. The mouse also comes equipped with a slot to store the USB plug on the bottom.

In fact, the best feature of this mouse is that USB plug, which is almost flush with the back of my computer when plugged in. Most other wireless mice have plugs that stick out 1-2 inches. This receiver only sticks out about a quarter of an inch. This is the first wireless mouse plug I don't have to worry about forgetting in my laptop. I just toggle it on and off on the bottom and go!

Unfortunately, the forward / backward side keys are in a weird spot, particularly when using this right-handed. You have to move your pointer finger over in such a way as to be uncomfortable. Left-handers can click the forward / back buttons with their ring finger or pinkie, which is much more comfortable. You can even use your middle finger if you are *left-clicking* with it, which is the same as *right-clicking* with your right hand. So if you are ambidextrous, it's better to use this left-handed.

I found the placement of those buttons to be less than ideal when using either hand. They are so small that it's difficult to find them, and after not using them much it's easy to forget they are even there when you need them. They do work a little better left-handed, but in general I wish they were bigger and not so far off to the side.

CONCLUSION

This is a very good mouse that is great for mobile computing. The discrete USB plug makes it convenient for laptop users on the go. The small size means that over time those with medium or large sized hands will want to step up to a larger version. Some may decide that the nano-receiver is not worth the smaller mouse and choose the Logitech MX Revolution Cordless Laser Mouse or the Logitech VX Revolution Cordless Laser Mouse instead. Logitech has been adding to their lineup of mice that use the smaller mini USB receiver. That includes the Logitech V450 Nano Cordless Mouse- Black and the Logitech V550 Cordless Laser Mouse, among others. So unlike at the time I got the VX Nano, you do have other options.

Enjoy!

I've been using both the VX Nano and Revolution for several months now. In the end, I prefer the feel/design of the Revolution.

Here's why I prefer the Revolution:
- The size is just perfect and easier to get a grip.
- The scroll wheel is also larger/durable - hyperscroll works better.
- Has a real middle button (The Nano uses the middle button to toggle between hyperscroll/regular scroll)
- Two more extra buttons (zoom in/out)
- Back/forward button is located near the thumb (whereas you have to use your index finger for the Nano)
- Uses just one AA battery (The Nano requires two AAA batteries)
- VX Revolution can be suitable for desktop use also.
- USB receiver can be easily stored and removed (for the Nano, you have to open the battery cover to store the receiver [but then again, one really doesn't need to store it for the Nano, since it's already convenient to keep it attached on the laptop forever]

Pros about the Nano:
- Obviously the receiver is the biggest selling point. It's nice to keep it on the laptop and really just forget about it.
- You can alternate between hyperscroll/regular scroll just by pushing down on the scroll wheel. (However, this could also be a con for some because you end up sacrificing a real middle mouse button. For the Revolution, you have to move a switch on the back of the mouse)
- It comes with a case and USB extender (for desktop use [although the design/size of the Nano is really more for laptops)
- Suitable for both left/right hands. (Left handers were left out [no pun intended] on the Revolution.)

I'm sure most people will find the Hyperscroll really awkward at first; I certainly did. However, once you get used to it, there's no going back. It 's just so much better with less effort to scroll than the "old generation" scrolling techniques. It almost makes it feel like your computer becomes faster, since you can navigate long folders, websites (especially forums), and email effortlessly.

My main problem with the Nano, being a much smaller design than the Revolution, is the scroll wheel. The wheel on the Nano is almost half the size of the Revolution. It just doesn't seem as durable and actually requires more effort to spin. Unfortunately, the hyperscroll on the Nano stopped being so "hyper" after awhile. The hyperscroll is supposed to spin the mouse wheel continuously with just one thrust of the wheel. However, it only spins for about a second now before the wheel stops completely (for the Nano). I sent it back to Logitech and it was a painless effort to get a new replacement (they even paid for postage). I was happy with getting a new Nano with a working hyperscroll again. However, after a few weeks of using it, I'm getting the same problem again. Logitech really should look into this design flaw. Whatever the mechanism part is, which allows the hyperscroll (many seem to state it is the small rubber ring inside), seems to not last the test of time. I've yet to have this problem with the VX Revolution (I guess the larger rubber rings last a little longer?).

Both has it's pros and cons, but in the end, I really prefer the Revolution. If you plan on using the mouse for laptop and desktop, definitely go for the Revolution (assuming you're right handed) - no question. Ultimately, it would be great to have a VX Revolution mouse with the nano receiver (and for the hyperscroll to last forever).

If you've ever had to replace your computer mouse, then you know that Logitech covers a wide range of the market, from wireless to corded, from tiny to ergonomic, from no-frills to bells-and-whistles. The VX Nano Cordless was designed specifically for use with laptops, although it can be used on desktops.

The "Nano" refers not to the size of the mouse (it is *not* one of those ultra-portable mini mice) but of the wireless USB transmitter. When plugged in, the transmitter extends a mere 1/4 inch; you can leave it attached, slip your notebook into your case, and carry it away without worrying about snapping it off. If you choose not to leave it attached, the mouse itself has a storage compartment underneath that locks in place so you don't lose it. The mouse itself is 3 3/4 inches long, with contoured, rubberized sides for a comfortable grip. The mouse might prove to be too small for large hands, although most people won't want anything larger for their laptops. It beats the mini mouse I have and rarely use.

The tracking sensitivity of the mouse is excellent, and the scrolling feature is lightning quick. Although you can plug in the Nano and start using it right out of the box, you need to download the installation software to take advantage of the more advanced features such as internet search (really cool!) and browser back/forward at a touch. (Mac users have to download the appropriate installation software at the Logitech site, while Windows users can use the enclosed CD.)

The VX Nano comes with two AAA batteries, a soft case, a Windows installation CD, and an adapter for desktop use. The adapter is primarily for computers that do not have a USB connector at desk level; it consists of a USB connector at the end of a cord, with a port for the transmitter. The port is lightweight and can be easily skewed by accident, but its flat bottom keeps it from tipping over. I have an older Mac desktop, with a low-speed USB port on the keyboard, and I was able to plug the transmitter directly into the keyboard to use the mouse.

This device works as well on my MacBook as it does on a Windows laptop. Going online to download the Mac driver doesn't take any longer than it does to slip a CD into the drive and install from there. The only flaw I discovered occurred when I opened the back of the mouse while the transmitter was still plugged into my laptop's USB port, which turned off the mouse power; my laptop displayed a message that it needed to be rebooted, and the screen was completely frozen, disabling the normal restart/shut down menus. I learned quickly that I had to remove the transmitter *before* opening the storage/battery door.

I own two other Logitech mice, but this is by far my favorite. However, no-nonsense laptop users who plan to navigate documents only might find this mouse too pricey. I, however, have already packed mine in my laptop case, where it will travel from home to work and back again.

After being disappointed several times by Bluetooth models, I decided to give this one a try. Strangely enough, the primary reason I selected this mouse was because of the tiny receiver; I chafed at the thought of having a monstrously large piece of cheap plastic sticking out of my MacBook. Shallow, I know, but at least I admit it. Overall, that aesthetic quirk of mine ended up being my most beneficial flaw, as the VX Nano is the most incredibly reliable, accurate, and practical mouse I've ever owned.

The box contains the mouse, a carrying case, the receiver, batteries, and Windows software. As noted in previous reviews, Mac users such as myself have to journey to the Logitech website to download software for the mouse -- though it's hardly required, as it will work as soon as you plug in the receiver.

Since I'm in print/graphic design, I was particularly worried about its tracking abilities. My fears were groundless, as this mouse is about as accurate as they come. It offers pinpoint control, so working on those fine details in photos or layouts is a breeze. The mouse clicks with a good feel and sound, and the medium size offers more control than the diminutive Bluetooth models on the market; additionally, you won't feel as though you're moving a paperweight around the desk, grunting all the while.

One feature that really blew me away, however, was the hyper-fast or free-spin mode of the scroll wheel. At first, I considered this a novelty, but quickly grew to believe it to be one of the mouse's best features. This is particularly true when I find myself working on a large document. The free-spin allows me to zoom through pages in record time. If you work on large layouts or documents, or if you have the patience of a two-year-old doing the potty dance (both apply to me), you'll love this feature.

Battery life is incredible, and that's a great bonus. Indeed, I had given up wireless peripherals in the past because they seemed to use enough juice to power Ohio. The VX Nano, however, is a sipper; in seven months of very heavy use, I've changed the batteries once. The receiver fits snugly in any USB port, and I've never even bothered to take it out when transporting my laptop. The back/forward page features are convenient, though I have found they don't always work.

Indeed, all the mouse's features are not available to Mac users such as myself. This hasn't concerned me, as most are things I would likely never use. So, when I consider all the other factors, I have to give the mouse the highest possible rating; Mac users need not fear this product at all.

One caveat: the mouse will wake up your Mac from sleep mode. I can thank my cat for discovering this. If the mouse is placed where it's likely it will be bumped, you might consider turning it off before putting your Mac to sleep. Or, you might just consider putting up baby gates to protect it from felines. Your choice.

The VX Nano is a great laptop mouse. The tiny USB transmitter is perfect for laptops, small enough so that you never have to remove it. The mouse feels great in your hand,and is very responsive. The wheel makes scrolling a breeze especially through long documents. One thing to note about this mouse is battery life. I've had the mouse for almost 10 months now and I'm still on the original batteries. The on/off button helps alot.

I've been using this mouse on a dual boot laptop with Windows Vista and Ubuntu Gutsy Gibbon. The mouse works fine in both operating systems. I don't use the included software since in Vista most of the common mouse functions are used by default. Under Ubuntu, I definitely recommend using btnx, it allows you to easily access the all buttons and customize them for use with Gnome and Compiz.

Now for the Big con-
The scroll wheel spins freely for the first month or so of use, then starts to rub. I have a Logitech MX Revolution for my desktop and I have the same problem with it. After taking the MX Revolution apart I found that Logitech had left the smallest amount of clearance between the wheel and the mounting points for the wheel. Because of these small gaps, any changes in the diameter of the wheel would cause the wheel to rub. What would cause the wheel diameter to change you ask? Well, the wheel is surrounded by a nice rubber pad to make spinning the scroll wheel easier. Turns out this pad is just a rubber ring that seats into a groove in the wheel. Over time, these rubber rings started to stretch and become loose. This caused the rubber ring to rub against the scroll wheel mounts. I first tried to glue the ring down, but that didn't work. The only thing I could do to fix this problem was to remove the rubber ring completely. This worked for both the MX and VX mice. I haven't noticed too much difference without the rubber pad, but it isn't as comfortable on my finger. This is a major problem with this mouse. I don't know if anyone else has had this problem, but it does affect usage. Now I have become accustomed to using the wheel without the rubber, and other features of the mouse make it worth keeping so I do recommend this mouse.

GENERAL INFO:

The Nano Mouse is a cousin to Logitech's regular sized VX model. In size it's about ½ inch smaller than the VX, and a bit thinner. It fit my mom-sized hand nicely, and my husband hasn't complained, but I rather imagine that it could be too small for someone with really large hands.

The other shape-and-size element I noticed is that the mouse is symmetrical which means theoretically that it has no inherent lefties or righties bias. The theory falls apart somewhat as there are two programmable buttons on the far left side of the mouse: Logitech calls these Thumb Back and Thumb Forward buttons. I found them difficult enough to use as a rightie, I can only imagine it would be more difficult for a leftie.

The package includes a carrying case, batteries (the ones in the box were dead) and Windows-ONLY software. I tested the mouse on my MacBook and an ACER laptop. The mouse did work right out of the box on the Mac (once fresh batteries were inserted), but without the 'special features'. To get those to work you need to go to the Logitech site. The file you need is icc222.dmg - a quick download.

The key element is the minuscule RF dongle that goes in a USB port. [Bluetooth afficiandos are just going to have to wait.] It's so small that you hardly need to remove it, unless you use a very small tote. If you do want to remove it, there is a convenient storage area inside the mouse.


REGULAR FEATURES:

Left and Right Buttons: can be set for 1, 2, and 3 clicks as well as click-lock and right click only.

The Scroll Wheel lets you adjust increment and acceleration. Typically a small movement is one line, a big one 5 or more lines (varies, of course, with what Application you are using).

There is also an extension 'thingie' for those looking to use it with a big box machine.


COOL FEATURES:

The Scroll wheel lets you go left and right. That's right you can now nudge the pointer over. How cool is that.

One-Touch search: Behind the scroll wheel there is a button with a magnifying glass on it. You can program that button to load up a search function such as Yahoo, Google, Finder, Sherlock, or even a custom URL.

The Thumb Forward/Back buttons can be programmed to do various tasks. There are more options available on the Windows menu as compared to the bare listing for Apple machines.


PROBLEMS:

--The BIGGEST problem is that the dang mouse software locked up my MacBook. It is really difficult to do on a Mac so I can only conclude that Logitech thought of Apple as an afterthought. Boo-hiss.

--The above opinion is supported by the second annoyance which is that they didn't include the Apple software on the disk.

--The 'nudge' feature does not work in Open Office (on the Mac) - sigh - although it does work in Adobe. [Note: this feature worked with everything I tried on my Acer.]

--They also could have, for symmetries sake, included another set of programmable buttons on the right hand side of the mouse for lefties.

WINDOWS/INTEL RATING:

Four Stars [B+]. This is a nice sized mouse with some cool features. The software is a little slow installing but partially that was because the installer found an upgrade to download. I would definitely consider buying this mouse for my Acer laptop. The Zoom programmability and other programmable features work in Open Office, MSWord and Adobe and would make my life easier.

MAC RATING:

Two Stars. [D+] The Nano is a nice mouse but it wasn't designed with an Apple user in mind. The software had to be downloaded from the Logitech site and even then the presentation was inferior to that offered for Windows. Some features like Zoom are not available to us -period.

So, although the Nano has some cool, advanced 'programmable' features, I can't say that I'd recommend it to Mac users. That is, unless you are one of those vigilant sorts that can manage to remember not to let your computer go to sleep without turning off the mouse. Otherwise, it is going to trash your kernel. And I can't begin to tell you how annoying that was.

The Logitech VX Nano Cordless Laser Mouse for Notebooks is a very good product that fills a big need for mice: a powerful and convenient wireless mouse for mobile use. You can use this mouse for your desktop. But it's really ideal for your laptop on the go. Sure you can take any mouse with your laptop, but the short receiver, small size and included travel case make this mouse extra portable.

Over the past year of using this mouse, I have come to further appreciate its good features as well as become more aware of its short-comings. This is still one of the better laptop mice you can get, but the size makes it better suited for those who prefer smaller mice. Those with small hands will naturally find it more comfortable. Don't get me wrong: even those with large hands can get used to it. But for heavy users who are on their computers for hours at a time, the small size may become uncomfortable. I have found that even though I have small hands for a man it's just not as comfortable as some of the larger models.

PROS:
+ The tiny receiver works great! Leave it in your USB port or store it in your mouse!
+ Great smooth underside and laser pointer let you use it anywhere; no mouse-pads!
+ The side grips have a nice dimpled texture for moving your mouse in comfort
+ The included buttons (L-click, R-click, forward, back, slow) are just enough for most users
+ The buttons can be reprogrammed, though only the *slow* button behind the scroll is worth possibly changing
+ The LED light on top alerts you to a weak battery and when turned on or off
+ The premium scroll wheel switches from normal to turbo with a quick press; can be used to "click" or "hyper-scroll" for normal to superfast scrolling
+ Nice convenient storage compartment for USB receiver inside the mouse
+ Convenient On / Off button for conserving battery power when not in use
+ The AAA batteries are convenient and will last a few months between replacements
+ Great comfort for those with smaller hands, like women and teens
+ The mouse works for right and left handers; lefties need to click the forward / back buttons with their ring finger or pinkie

CONS:
- The size of the mouse will be too small for extended use by those with medium sized or larger hands, including most men; might be OK for short stints, but over time it becomes tiresome

Logitech has been adding to their lineup of mice that use the smaller mini USB receiver. That includes the Logitech V450 Nano Cordless Mouse- Black and the Logitech V550 Cordless Laser Mouse, among others. The updated Logitech Wireless Anywhere Mouse MX for PC and Mac is probably the best comparable option. So unlike at the time I got the VX Nano, you do have other options.

Enjoy!

This would have been a great mouse for me, except for one MAJOR problem.

The VX Nano's receiver got STUCK in my computer's USB port. Some USB ports have prongs that angle outwards on the left and right side on the inside of the port in order to keep devices snug. Logitech was not so smart in that they put holes on the sides of the receiver's jack that line up with the inward facing prongs. So when you put the receiver into USBs that are designed like this, they go in, but will not come out, because the holes on the left and right of the receiver catch the inward-facing prongs.

I know this, because I finally had to use pliers to pull the receiver out and when I did, the prongs in my USB ports were facing the other direction - one even broke off. Luckily the USB port still works, but the receiver snapped off the metal USB piece. The receiver is now separated from its USB connector Sending this thing back to Amazon. So frustrated.

CHECK YOUR USB PORT BEFORE YOU PUT THE RECEIVER IN - MAKE SURE IT DOES NOT HAVE ANY PRONGS ON THE LEFT OR RIGHT SIDE THAT MIGHT LOCK YOUR RECEIVER INTO YOUR USB PORT!!!!

i first came across the nano when helping my sister pick out a new mouse for her laptop. my girlfriend's mom had the revolution which i thought was a pretty decent mouse at the time, but the nano had just come out and seemed to be a small little upgrade from the revolution so my sister went w/ the nano.

my first impressions were not the greatest. the mouse is small. that's just about anyone's first thought when seeing and touching it, and it's hard to see anything other than that at first. i use a logitech mx 1000 on my computer, which is by all accounts a huge mouse. but it's comfy and roomy, and my favorite mouse to date. but shortly thereafter, my girlfriend got a nano for her laptop, so i was forced into using it fairly regularly. w/in weeks i found it almost impossible to use my mx 1000.

the nano is lightening quick and more responsive than any other mouse i've ever used. even cranking up the sensitivity/pointer speed on the mx 1000 leaves it feeling sluggish.

the size of the nano quickly became a non issue. once you use it a few times, your hand adjusts to the size. my hands aren't freak show huge, but they are on the larger side of things(the only reference i can think of is that i can palm a basketball) and the nano fits just fine in my hands.

out of the box the buttons aren't configured the best (having the middle button change programs, and NOT act as a middle button), but they are all fully configurable. once set up properly the mouse really shines. having the middle button as an actual button, and not a wheel click, is a luxury i didn't know i wanted until i had it. again, going back to my mx 1000 is a clumsy affair.

the scroll wheel, in either mode, outshines all others i've used as well. the frictionless is a great mode when you want to jump to the top or bottom of a document/web page quickly. it's a huge leap from the old up/down scroll buttons.

the receiver is almost comically small. it's ron popeil "set it and forget it" small. in either a laptop of a desktop it's just nice to have a receiver plugged into your usb port that you don't have to worry about getting caught on.

the one negative i could find in the nano is that it doesn't have rechargeable batteries in it. but as a "portable" mouse i can understand that there is no rechargeable base to be found. toss in two aaa rechargeable batteries of your own and you're all set. or use regular batteries, it doesn't really matter, because the battery life in this mouse is ridiculous. like six months of 10+ hours a day of use ridiculous. the logitech software will keep track, in days, of the remaining battery life, and i've found it underestimates as well. i've gotten down to three days of life and stayed at three days for... three days. this may be the most energy efficient piece of technology i've ever used.

all in all, as weird as it is to gush over a mouse, this mouse is worth gushing over. it's ideal for laptops or desktops and outclasses everything else available. unless you've got shaq sized hands, i cannot see anyone being anything less than happy w/ this mouse. i wouldn't recommend any other. great work logitech.

I've never really been sold on wireless mice. For laptops, the receivers were always too large and threatened to break off or damage your USB port and they just didn't make sense to have on a desktop. After all, why should I need a wireless mouse when the cord is never in my way? This little guy, however, changed that. The receiver is so small that I don't have to worry about breaking it and now that I've used a wireless mouse, I see just how much more maneuverable it really is.

One person stated in a two-star review that the mouse doesn't turn itself off when you stow the receiver in the mouse. This isn't true. The mouse does turn itself on and off automatically when you take out or insert the receiver respectively. The key thing with this mouse, however, is that the receiver is small enough that you might forget that it's still plugged in when you stow your laptop away or walk away from your desktop for a long duration, so you'll need to remember to turn it off periodically. The mouse does come with a nice case (I'm not sure I really needed to pay for that invisible zipper) in which I'll be sticking a note card that says, "mouse off?" to remind me to check.

This is, by far and away, the most comfortable ambidextrous mouse I've ever owned. The most comfortable mouse I've ever held is the MX Revolution, but If you're a lefty, this is a great option for you. However, anyone considering this mouse needs to try it before you buy as this mouse is not meant for people with large (possibly even just average) sized hands. I'm sure this is on purpose and part of Logitech's definition of portable, but I've rather small hands for a guy and I defiantly wouldn't want this mouse to be any smaller.

One thing I always take into consideration when opening a gadget for the first time is the packaging (read: I hate blister packs that have to be cut open and ripped apart which subsequently decide to return the favor by cutting and ripping open a nice wound on your hand), and I have to say that Logitech really did it right. Everything folds open, slips or pops out without too much effort.

The 'center click' is where I wish I could give this mouse 4.5 stars instead of 4 or 5. On a traditional mouse, you get a center click button by pushing vertically down on the scroll wheel. On this mouse, however, pushing down on the scroll wheel toggles your scrolling style between a fast scroll (think: holding the front of a bike in the air and giving the front wheel a spin) and traditional 'click' scrolling. This feature is great; it's wonderful to be able to zoom from the top to the bottom of the page with a single stroke and not need to reach for the keyboard. However, the center click button is the one in the middle of the mouse with the magnifying glass icon on it. Mozilla and Firefox users will agree that this is a poor position for regular use and probably would be better located in front of the scroll wheel instead of behind. Despite this, the button is still rather accessible to your index finger.

Quick note to Mac users: There's one tiny note on part of the packaging saying that you need to get the Mac software from the Logitech website for the mouse to work. Don't know if this is 100% true or not, but seeing as Logitech doesn't advertise this fact especially well, I thought I'd mention it here.
