5.0 out of 5 stars A truly high-quality mouse, June 7, 2005

This review is from: Kensington 72121 Mouse-in-a-Box Optical Elite USB Mouse (PC/Mac) (Personal Computers)

I have nothing but good things to say about this mouse. Kensington is legendary for the quality of their mice and input devices, and this mouse continues that tradition, despite its low price. The 5-year warranty is very reassuring, and Kensington tech support is unbeatable (in the unlikely event that you need it). This mouse is very comfortable for both right-handed and left-handed users. It is extremely accurate and precise, and works flawlessly with Macs as well as Windows PCs. I use this mouse on a wooden desk without a mouse pad, and it works perfectly. I've also tried using it on my carpet, on my coffee table, and even on my leg, and it worked great! I can say with confidence that this is a go-anywhere mouse that truly doesn't need a mouse pad in order to function. The MouseWorks software is arguably the best mouse driver ever written. My only complaint, and a minor one at that, is that I wish it came in an all-black version, rather than black & silver. Other than that, I would heartily recommend it to anybody who wants a premium quality mouse at a reasonable price.

5.0 out of 5 stars The only mouse so far, January 20, 2010

This review is from: Kensington 72121 Mouse-in-a-Box Optical Elite USB Mouse (PC/Mac) (Personal Computers)

Environment
This mouse was purchased for a new Mac Pro 2.93 8-core system to be used in a 3D modeling, graphics environment along with other Macs that have the previous generation Optical Elite Kensington mice.
Low light, Placed on corner station desktop, plenty of room.
No games are on the system.
Moderately low amount of text (typing).
Heavy use for graphics, drawing and modeling. Average day use is around 10-14 hours.

Physical (User)
6'2" (186cm), Hand span pinky-thumb 10" (25.4cm), medium-long fingers.
OCD about hand cleanliness, wash 12+ times a day
I have used mice since 1987. Many brands and in 1995 I switched to Kensington mice for all my machines; Mac and PC.
I have had 2 of the 4 button Kensington mice since 1995 on ADB port macs, they still work. I have had 3 Optical Elite 4 button since 2001, they still work. They all function well using the Mouseworks software.
Typically I use Left Click, Double Click, Control+Click and Popup menu function with about 15 functions programmed in Mouseworks.

Physical Aspects:
Kensington 72121 Mouse-in-a-Box Optical Elite USB Mouse is 1.5" tall comparing to Apple's mouse shipped in 2009 at 1.25". While many think of it as a little too tall you should consider that that extra 0.25" in the hump height allows clicking to be performed from the knuckle joint of the fingers, index and middle. On the Apple mouse I find myself, and a few others to squeeze and use the first phalange joint to click the button which is actually the whole top of the mouse. If you are aware of ergonomics principals and guidelines you will note that keeping fingers moving from knuckle is preferable to phalanges.
If you have a medium to small size body and hands and are sitting in a chair such that the height is not optimum for the wrist angle you should consider using a gel pad for the wrist area.
The surface is comfortable and the grip area on Left and Right is very nice to hold on.
The Left and Right button are conformable and so are 3rd and 4th on two sides. The scroll wheel is rubber like; it has good grip on it and the button on it functions well. (Swap Scrolling direction)
The Left and Right buttons chording (pressing both buttons at the same time) functions well. The 3rd and 4th button can easily be chorded by squeezing the mouse with the 3rd phalange of the ring finger and the thumb. The wheel can be depressed as a button to change/toggle the direction of scrolling from vertical to horizontal. You can also have an indicator in the top menu bar (Mac) to show that it is on Horizontal. If you kill that function you can program the wheel button as any other button, turning the 72121 to a 7 Button mouse.
The chord is 6ft long. I have seen a post about it containing lead. That is NOT in any documentation, on the box or any other place than I can think of. The concept is very retarded as lead is one the poorest conductor of electricity due to lacking of free electrons.
This mouse does not really need any maintenance. I just clean the bottom every 2days on a low moisture dust cloth. Keeping the surface clean helps a lot, especially if you use hand moisturizers, creams, etc.
I have never had any of my 11 Kensington mice to have any wire problem, alas, I do not pull on them and I do not hang the mouse by the wire or use it as a spinning weapon.

Software:
The Mouseworks software works great; it is the most complete mouse software I have seen. You can assign many functions and macros to the buttons and streamline your work. You may even setup different sets for each button for each application. e.g. In most apps I use Left Click, Double Click, Control+Click and Popup menu function. The chord left and right buttons OPENs or COMMAND+O in Mac or same as Control+O (PC) and Chording the 3rd and 4th button performs a CLOSE; COMMAND+W or CONTROL+W. But in Safari and Firefox I use the front chord for BACK button of browser and the back chord to close a window.
Some functions can make your life much easier. The popup menu allows me to enter my email address, (3 of them) with one click without ever have to re-spell it or copy and paste it, address, phone numbers and even the commands that are repeated a lot in certain software.
There are a lot of adjustments for acceleration and deceleration of the mouse so you can really appreciate that if you have more than one monitor and have mover the mouse a lot to go from one end to other. Scrolling speed is adjustable, so is clicking speed. Unfortunately you can not chord the front and back buttons together. Basically this is a 7 button mouse while Kensington could have had the software to allow more combination for chording to make this to be 13 button mouse.
To make the easiest path for installation your best bet for this mouse is to download and install the newest version of it first and repair permissions, then restart. It is 3.0 for Mac and it works with Mac OS X 10.4.11-10.6.2. The CD version that comes with it is not going to work with the Mac Pros and new iMacs.


Conclusion:
I recommend this mouse to anyone who wants to be able to make their hand to have less repetitive tiring. Faster function and less stress. The software is very easy to set up and expand. You can even setup the mouse on one Mac and then copy 2 files to another mac and reboot and have the same software setup for both.

5.0 out of 5 stars Kensington Rules!, September 3, 2002

By 

Lorin Rivers (Austin, TX United States) - See all my reviews

This review is from: Kensington 72121 Mouse-in-a-Box Optical Elite USB Mouse (PC/Mac) (Personal Computers)

I love this mouse, and I love this company. They really "get" it, from design, to drivers, and most importantly, service.

This mouse is comfortable, and addresses the only flaw of its predecessor (a tendancy to slip when pressing the side buttons on the body of the mouse). I bought that one the day they announced Mac OS X drivers and threw the other mouse I had (rhymes with "blech") in a drawer.

This mouse has all the buttons you could want, but not to a ridiculous extreme, and supports "chording" where you can assign additional functionality to multiple-button presses (i.e., both main buttons at once).

Buy this mouse instead of some other company's!
