From the Manufacturer

Tune for the way you play.

The G9 Laser Mouse is built with advanced customization technology so you can tune your mouse for your playing style. It comes with two interchangeable grips from which to choose for your preferred comfort. A 3200 dpi full-speed USB laser engine with adjustable dpi, as well as onboard memory that stores up to 5 mouse setting profiles, give you the most advanced performance. For more control, the G9’s weight tuning system allows you to add up to 28 grams of additional weight, while the exclusive MicroGear™ Scroll Wheel lets you switch between modes -- click-to-click and hyper-fast scrolling. Finally, custom-color LEDs let you customize the G9 look for a mouse that’s all your own.

Customer Reviews

Good mouse, has 1 problem
The only problem I have with this mouse is the size and the hard textured cover for this mouse is also textured on the bottom section of the mouse. Since there is texture on the bottom of the cover, it slows the mouse movement down. A bit of sandpaper does take care of the problem though.

Too small
The Bad:
It's too small for medium to large hands, unless you're a claw-gripper. The smooth default grip is nearly useless unless you are a child or have small hands --- it's too small to palm, and too slippery and "velvety" to claw. So you'd spend more time trying to hold onto the mouse than actually working or playing. Sadly, the smaller interchangeable grip is the grip of choice if you're a palm-gripper, when it was designed for claw-grippers. The center of your palm will never be supported, leaving a gap of air.

The thumb-buttons are set too far back, causing me to retract my thumb before I can hit the "back" button with my thumb joint. This simply won't do for gaming. If I place my hand further back to accommodate the thumb buttons, then my palm won't be supported by the mouse at all, which makes me have to claw the mouse with my fourth and pinky fingers.

The Good:
Scroll wheel "MicroGear" works like a charm for scrolling quickly and stopping precisely at the portion of the page you want. This feature, along with Logitech's great mouse feet, makes it a little difficult for me to ditch the mouse.

Conclusion:
Since I still have my MouseMan Optical Dual Sensor mouse (Logitech), I periodically compared the grip comfort between the two mice. There is really no contest... the old old MouseMan's chassis is by far superior to the G9, for large and medium hands. There is definite palm arch support with the latter (and I suspect with the G5 as well). Whereas my hand (or any of my buddies') can't climb on the G9 at all and rest on top of it.

Get the G9 if you are a clawer. For palmers, look elsewhere. I'll be returning this unit before it causes me joint damage.

Middle Mouse Button Requires Force
In addition to all the other reviews, I'd just like to add that the middle mouse button is very difficult to press. It requires a ridiculous amount of force to push down. I died many times in various FPSs because I couldn't hit the middle quickly enough. Fortunately, this is fairly easy to fix: either change the middle mouse button to one of the secondary buttons using the downloadable software, or just change the key binds for any games you play. Other than that, this mouse is very good, and I'd recommend it to anyone who has the cash.
