I can't say anything about this cordless mouse, but in general you get what you pay for when it comes to wireless mice. I've used a lot of different wireless mice of all shapes, sizes, ages, etc. As far as gaming, I have an mxduo and my mx700 will hang with anything out there. I would also like to point out that my friend, who got invited to a national quake III tourny in texas uses the same setup and so do plenty of gamers. Not to mention, Maximum PC did extensive testing themselves and had reputable gamers report their own findings, which brought them to the decision that it was the first and ,might still be, the only gaming worthy cordless mouse. IMHO the only advantage of wired gaming mice is the on-the-fly variable dpi feature that some have. Great for games like BF2 when you switch from a not so accurate tank (where you want low dpi) to using a very accurate sniper rifle where you want to make very precise aiming adjustments(high dpi, the selling point of razor mice)
