"Overall the Razer Diamondback Plasma LE is as perfect a gaming mouse can be as anything better than this would have something to do with lazer sensors. To be short, the Plasma LE is the best in its class. The mouse provided excellent responsiveness, thanks to its 1600 dpi infrared sensor and always ON mode. As for starters, this mouse may be a little too fast for you but fret not because the driver lets you adjust different types of sensitivity and speeds. Changing sensitivity without having to use the "Alt+TAB" button is also possible with the "On-the-fly Sensitivity" feature. Gamers will certainly love this feature as it gives total control over the mouse, which is a critical point for professional gamers."
