I go through computer mice on a fairly regular basis. I don't abuse them, but I use them a lot, and in multiple capacities. From web browsing, to gaming, to image manipulation, to video editing, I do a little of just about everything. As a result, I NEED to have a mouse I can depend on.

After burning through several Razer branded mice over the last few years, I decided to go to a different manufacturer this time around and see what else is out there.

I had been using a Logitech M510 wireless mouse as a stand in after my last mouse died, mere weeks after the warranty was over with. It did the trick, but suffered, as apparently just about all wireless mice do, from drop offs in the signal and a lack of smoothness that one gets with wired mice.

My criteria was that it had to be wired, not molded for right-handers (I'm a lefty), and doesn't require one to mortgage their house to buy it.

I was pointed, via message boards, to the Steel Series Sensei MLG Pro Grade Edition. After doing a bunch of reading, I decided to give it a try.

From the moment I plugged it in, I was in heaven. I went to the website and downloaded the special software for the mouse so that I could fine tune it, although even without said software, it already felt amazing.

The tracking on this mouse is very good - no dropouts and a precision that I haven't experienced before. You can use the mouse software to fine tune everything from the DPI, to how high you can lift the mouse from the surface before it stops tracking. Plenty of extra buttons, including one that lets you double the DPI on the mouse on the fly, makes for a smooth experience whether you are surfing the web, or playing a video game.

Size wise I found it perfect. I have long fingers, so short mice don't work well. With this mouse I can comfortably click any button without a second thought, and experienced no discomfort even after using it for long periods of time doing photo-retouching in The GIMP.

Features like changeable led colors for the wheel, and back, along with a customizable graphic on the bottom are not the reason I got this mouse, but they are "neat".

The mouse might be a little pricey for some, but if you need something that won't give out on you and is very customizable, this could be the mouse for you.

I've had this mouse for exactly two years and one day, and a few days ago it started double-clicking. I use this fairly constantly (every day, sometimes for 4-8 hours at a time) for general purpose, including gaming of course. This makes it completely useless to me now. For the $80 price tag (as of posting this, it's listed as $130, which is entirely unacceptable), I expected it to live longer than that, even if I did use it as heavily as I did.

Good mouse, feels great, collects dirt like crazy (constant cleaning), very accurate, and portable. Just don't expect it to last more than a year or two.

I have a mac and I have this mouse and the sensei raw mouse.

This mouse has a number of enhancements over the raw:

- It has an LCD panel underneath that lets you tweak and save most settings without a driver
Press the CPI button for 5 seconds and turning over the mouse, you can use the scroll wheel to change the settings.

- it has acceleration tweaks the raw doesn't have (I love the exactaccel / exactaim settings)

- you can save an image to the LCD panel (I put my name on the mouse)

Unfortunately, though you can save the movement settings in the profile, but you can't save the button settings.

This kind of negates the whole point of on-board profiles for me because I use my mouse left-handed.

This means if you're left-handed, the mouse will boot right-handed, and you have to log in and launch the
driver before the buttons are reversed and you can use your mouse correctly.

I would MUCH rather prefer to save the button settings on the mouse and go driverless.

I come from 4 years of using my Razer Lachesis 4000 DPI mouse, and I have used a few other mice as well. I was a bit skeptical about this mouse, since it was just released and it uses the fairly new Avago 9800 sensor, but I must admit, it works amazingly well. There is no noticeable acceleration (positive or negative) at all, and the mouse movement feels incredibly smooth, even on the "control" side of my Razer Vespula mouse pad. I absolutely love the customizeable colors, although the colors on the screen don't perfectly match up with the color the mouse changes, it works fairly well, and I managed to get a rather awesome looking green scroll wheel, off-white middle indicator, and orange MLG logo on my mouse that is very satisfying to look at. I also was able to effortlessly put my name on the LCD screen on the bottom, which is great for changing settings (especially CPI) on the fly. Although I don't game at extremely high CPI, the mouse supports up to 8200 CPI natively, and it can cheat to achieve a "fake" 16,400 CPI using the ARM processor on-board. Why anyone would need that high CPI is beyond me, but it does work. The mouse cord looks and feels very high quality, and the surface of the mouse isn't as shiny as I thought it would be. Coming from a soft rubber finish, I thought I would hate the surface, but it's the nicest looking mouse I've ever used, and it's much more fingerprint resistant than I imagined. Overall, this mouse is fantastic, and I would highly recommend it.

I play Starcraft 2 at a fairly high level, and this mouse is a huge upgrade from my previous Logitech MX500. I purchased it primarily because it does not require any drivers to be installed in order to configure it. Yes, I'm that sick of multi-megabyte mouse drivers. In about 30 seconds I was able to disable all hardware assist features and set the CPI to exactly what I wanted.

The mouse is very light, the tracking is very smooth and extremely accurate. I'm right handed, so the side buttons on the right are useless (too slow because of the angle), but the two on the left are perfect for thumb-clicking. I mouse at around 1350CPI @ 1920x1080, gripping the mouse with my fingers, hand anchored at the bone on my wrist.

Some users have complained about the mouse not responding if connected when starting up the machine - this is true. How do I get around it? I unplug the mouse and reconnect it in a different port. About 10 seconds of my life spent every once in a blue moon. No biggie.

Very satisfied, money well spent.

As much as I liked this mouse, I use it only sporadically one on of my systems. I plugged it in today (it has easily less than 24 hours of use on it). It is recognized by the computer, the buttons work, the lights work, the LCD display works, but the optical sensor is dead. No mouse movement. Occassionally, I can get it to jump about 100 pixels vertically.

Pretty disappointing.

This mouse was a nice upgrade from the SteelSeries RAW that made me fall in love with the design initially. I tried to stray to razer with their Deathadder (had tracking issues and a button worked selectively) and even the Ouroboros (COULD NOT find a comfortable grip which was weird with how customize able the mouse is) but I just didn't get the same precision and comfort that I got with the Sensei RAW. Needless to say I returned the two mice and instead invested in this beauty. NEVER an issue with tracking and it just glides effortlessly and comfortably across my SteelSeries QCK Heavy mouse pad. I think I am becoming a fanboy. Oh no.

This is an updated review for the SteelSeries Sensei MLG Pro mouse. My original review awarded only 2 stars. Since that time a significant problem for left-handed users has been solved and I'm very happy to raise my rating to 4 stars and edit my review accordingly.

This is SteelSeries' top-of-the-line mouse and, as far as I know, it is the second generation of this mouse. The original Sensei is still available and a "bare bones" Sensei RAW model is also available.

When my previous Logitech mouse began to "die" after barely a year of use, I launched into an exhaustive search for a replacement and I looked at every mouse I could find that had a chance of satisfying the following requirements:

1 - High quality -- Able to handle heavy (but gentle) use for at least 2 years.
2 - Either left-handed or ambidextrous design.
3 - Comfort for a large hand using a "claw" grip.
4 - RF wireless computer connection -- This requirement was dropped later (see below).

I couldn't find a non-gaming mouse that could satisfy the first two requirements. So most of the mice I examined were gaming mice. This created an unwanted side-effect: poor wireless choice. The reason is twofold: First, in order to be very fast and support high polling rates, most gaming mice are wired. Second, the few high-quality wireless gaming mice that exist have relatively poor battery life owing to their higher speed operation and computer connection. In the end I had to give up my fourth requirement.

Here are the models that made it onto my "short list" (in alphabetical order):

* - Cooler Master Storm Recon (wired)
* - Gigabyte Aivia Krypton (wired)
* - Gigabyte Aivia M8600 V2 (wireless)
* - Razer Deathadder Left-Hand Edition (wired) - out of production but still available
* - Razer Ouroboros (wireless) - unvailable when I needed to make my purchase
* - SteelSeries Kana (wired)
* - SteelSeries Sensei (wired)
* - SteelSeries Sensei MLG Pro (wired)
* - SteelSeries Sensei RAW (wired)

Noticeably absent is Logitech, a major maker of gaming mice. This is because I couldn't find a left-handed or ambidextrous model with sufficient quality. I've been using personal computers a lot since 1982 and I've had more failures of Logitech mice than any other.

Why I chose a Sensei
1 - I liked the overall design (the mouse shape and button arrangement)---for an ambidextrous mouse it's quite good. Of course, it's no match for the ergonomics of a dedicated left-handed mouse but the only left-handed mouse I found that approached the kind of quality I desired was the 2010 Deathadder and I don't think its switches are nearly as good as the Sensei line.

2 - The Sensei "tournament-grade" switches seem to work exceptionally well---I liked their light touch and positive tactile travel. Plus Button 1 and 2 seemed to be fairly forgiving as to where you press to activate them which aids comfort. (Some mice require your finger to be on top of the underlying switch and this may not be the most comfortable position for your finger with an ambidextrous design.)

3 - The Sensei line seemed like the "safest" choice because it had been subjected to some of the most rigorous testing by gamers, seemed to have many happy users, and was made by a company with an excellent reputation.

4 - The fact that every button is fully customizable, was another plus.

5 - The many adjustments available to the user were enticing, such as: the lift distance, sensitivity, motion correction, acceleration and precision.

6 - Finally, the larger-than-normal glide pads provide a very smooth movement.

Why I chose the Sensei MLG Pro
7 - It is a second-generation Sensei mouse.

8 - Up to four custom profiles can be stored in the onboard memory so they can be used when the mouse is connected to a tournament computer not running the SteelSeries Engine software. The Sensei RAW models do not have this capability.

9 - Although I would have preferred a wireless mouse, the braided cord on the Sensei MLG Pro is one of the best I've seen. It allows the mouse to move freely and resists entanglement. It seemed better than the rubber cords on the Sensei RAW models.

10 - I liked the "gun metal black" finish (actually, gun metal GREY). In addition to its good looks, it also seemed show the least fingerprints, oil and dirt.

11 - Generally, I dislike company logos on my gear and I find the stippled or dotted version of the SteelSeries logo on the other Sensei models to be unattractive. The "MLG" logo on this model isn't much better---but at least it is smaller and less obtrusive when it's backlight is turned off.

12 - Finally, I liked the ability to customize the color and brightness of the three backlight color zones of the mouse. The other second-generation models, the Sensei RAW mice, use monochrome illumination that has only two settings: on and off.

Now you know why I chose the Sensei MLG Pro. Next, I'll explain my impressions and rating.

My Impressions
I had high expectations for the Sensei MLG Pro. After all, it cost nearly a hundred US dollars! I ran into a few problems when I began---one was serious. But in the end, the mouse lived up to many of my expectations. Most of the "problems" were not actually the fault of the mouse and were easily rectified.

*--Left-Handed Operation--*
When I started to use the Sensei MLG Pro, I couldn't get the left-handed mode to work unless the SteelSeries Engine sofware was running. This seemed to contradict SteelSeries' claim that this is a "tournament mouse" and can be used with a tournament computer without SteelSeries software. Yet whenever I tried to use one of my left-handed profiles that I stored in the memory of the mouse, the main left/right buttons would always revert back to a right-handed orientation.

Fortunately, the problem was not the mouse or its profiles. The problem was with Windows' default mouse driver. When the Sensei MLG Pro is used with a Windows computer WITHOUT the SteelSeries Engine software, the native Windows setting for the main left/right mouse buttons will override the settings of your profile in the mouse. I tested this on PCs running Windows 8 Pro (64-bit), Windows 7 Ultimate (64-bit) and Windows XP (32-bit).

The solution is fairly simple: Configure the left/right buttons with Windows' own mouse settings. The rest of the Sensei MLG Pro mouse settings seemed to obey the on-mouse profile. Only the main left/right buttons (Button 1 and 2) were overriden by Windows own settings.

By the way, the SteelSeries Engine software is not included with the mouse. (No software disc is included in the package.) The software is free and you must download it from SteelSeries' website. Version 2.6.2760 is a 39 MB download.

*--Selecting an On-Mouse Profile--*
The SteelSeries Engine software is required to create and install a user profile onboard the mouse. This is fairly easy to do---the engine software has good instructions built into it. But selecting the profile once it has been downloaded to the mouse, caused me a bit of trouble at first because the instructions were not clear and the LCD display on the bottom of the mouse is not intuitive for first-time users.

When you scroll through the available profiles onboard the mouse, the current selection will be marked with an asterisk (*) to the right. This will show you if your selection has been implemented.

Here are the steps:

1 - Press and hold the triangular CPI button for 2-3 seconds.
2 - Turn the mouse over so you can see the LCD display and release the CPI button.
3 - Roll the scroll wheel to select the desired profile.
4 - Click the scroll wheel (push and release it like a button) to select the profile.
5 - A list of settings for the profile will appear beginning with "ExactSens".
6 - Roll the scroll wheel down the list to "Set as current".
7 - Click the scroll wheel to execute the "Set as current" command.
8 - Click the CPI button once to return to the profile list at the top of the menu.
9 - Your profile name will appear with the asterisk to show that it is now active.
10 - Click the CPI button a second time to exit the on-mouse menu.

Notes: The scroll wheel is used two different ways. First, your roll it to scroll up or down a menu list. Second, you click it to make a selection in a list. The pdf version of the Sensei mouse manual (which can be downloaded from the SteelSeries website) is wrong when it says you need to press and hold the CPI button for 5 seconds to activate the mouse's menu. You only need to press it for 2-3 seconds.

If you can't remember what profile is currently selected, use steps 1-2 above to view the mouse menu. Then roll the scroll wheel to see which profile has the asterisk (do not click the scroll wheel). To exit the menu without making any changes, click the CPI button once. Afterward, if the mouse seems to respond differently, you probably clicked the CPI button too many times and change the CPI setting. Just click it once more to toggle the CPI setting.

By the way, although you cannot change the backlight settings directly from the mouse menu, the on-mouse profiles that you create with the SteelSeries Engine software will execute the backlight settings you configured from the software. I used this feature to create a "Dark" profile which turns off all of the backlights so my mouse isn't so easily recongized by bystanders.

*--Wheel Operation--*
The only switch on the Sensei MLG Pro that I do not like is the scroll wheel. It does not spin smoothly. I expected the detents to be more subtle when rolling the wheel. Instead, the wheel has a rough, imprecise feel as you spin it. Plus, there is too much play in the actuation of the wheel switch. For example, you can roll back and forth between detents with no discernable action.

*--Failure to Turn On--*
When you restart your computer (a warm boot), the mouse will momentarily turn off. The problem is that it sometimes fails to turn back on. As far as I can tell, there are two ways to get the mouse working again. (1) You can unplug it from the computer wait a few seconds and plug it back in. Of course, this procedure will aggravate you if your mouse is plugged into the back of your computer in a hard-to-reach location. (2) You can shut your computer off, wait a minute, and turn it back on (a cold boot). This will aggravate anyone who is in a hurry.

I don't remember ever having the Sensei MLG Pro mouse fail to turn on when doing a cold boot. I think the problem only happens when doing a warm boot.

A "trick" that might work is to move the mouse while the computer is warm booting. I have to reboot often (I'm a software developer) and gently moving the mouse while the USB ports of the computer are initiliazed seems to prevent the mouse from hanging on reboot.

*--US/Canada Warranty--*
For unknown reasons, SteelSeries seems to hide its Sensei MLG Pro warranty. According to SteelSeries' support website, the warranty in the US and Canada is only one year. The rest of the world gets a two-year warranty. As a pro-grade mouse, I expected a 2-year warranty in the US. Perhaps SteelSeries should pay attention to its competitors like Gigabyte who provide 2-year warranties in the US for similar peripherals.

My Rating
Overall, I think the Sensei MLG Pro is a very good mouse and came the closest to satisfying my tough requirements. In my opinion, its positives outweigh its negatives by a wide margin. But it doesn't earn 5 stars. The scroll wheel, turn-on problems and mediocre warranty combine to cost 1 star.

It lives up to its tournament pedigree as a worldclass gaming mouse with powerful on-mouse processor, memory and profiles, plus myriad features. It's high-quality constuction should provide greater longevity than most other mice. If you want a pro-level ambidextrous gaming mouse that you can carry to tournaments, this may be a good fit. It has my recommendation.

I purchased my SteelSeries Sensei MLG Pro mouse at Amazon and used free shipping.
