My Razer Lachesis finally stopped working on me after 6 years of use and I decided to try a new mouse today. I picked up the Steelseries Sensei and I'm not all that happy with the quality and acceleration of it. It also makes my hand sweat and I've never had that problem before. The best thing about it was the scroll wheel and all the options available. Would anyone happen to have a suggestion for a good gaming mouse with a laser with minimum of 4000 dpi?
