OCZ Technology Behemoth Black USB Wired Laser Gaming Mouse

Pros: 3200 Dpi, multiple profiles, mouse accuracy. Most of all it fits my hand which is larger than the average male

Cons: sometimes the mouse needs reinserted when rebooting windows on windows 7 (x64), windows xp (x64), and windows vista (x64)

Overall Review: ridiculously comfortable as long as you dont game with your middle finger on the scroll wheel

Pros: Great mouse
*Adjustable DPI settings, you can customize the 4 DPI presets using the utility in the disk to anywhere from 0?-3200, so your not stuck with default sensitivity.
*Perfect size for my hands
*The wheel is sturdy and well built. I tend to break the mouse wheel first, and it will be hard to break this one. It also doesn't make a lot of noise when scrolling or clicking, too bad its not tilt wheel.
*5 buttons and 2 Hotkeys for DPI and profile change
*mouse cord
*Only 30$

Cons: *Takes time to get used to the ergonomic form
*Bright LeD, almost like a nightlight, and a little distracting when playing games.
*The mouse frequently doesn't responds to doubleclicks, or responds as a rightclick when you doubleclick. This is a huge problem. Might be related to generic drivers

Overall Review: In my case i didn't find the mouse to be too heavy at maximum weight, it was easy to pickup and you don't have to lift it too high to reposition.
