Thoughts: Razer Diamondback Mouse (LE)

Well…what can I say? This mouse is very sensitive…absolutely no skipping that is associated with other optical mouses that I have used. It has an awesome blue glow where even the scroll wheel lights up.
The mouse itself fits very comfortably in my hand and the two large buttons allow me to move my fingers around without worrying about them not being within contact range.
The scroll button (button 3) doesn’t depress much at all and there’s substantial force back that gives it a very sturdy feel. Scrolling itself feels solid like there’s power and authority behind each movement.
There’s 4 other buttons on this mouse but since I never ever use those buttons I couldn’t care less other than that they’re not in the way. Others have found the position of the 4 other buttons a bit tricky but they’re perfect for myself (I am a keyboard user for many tasks).
The sensitivity of this mouse shocks me as I can move across a single screen within only 1 inch of physical movement.
For CS:S it is rather nice and the minimal movement has gotten me a few extra kills. I do need more practice and need to find the right level of sensitivity in order to make this work really well. Needless to say, there were a lot of headshots.
Best mouse I have ever owned and a lot cheaper than most.
