This optorite mouse looks like a cheap knockoff of the logitech laser mouse.....I've had the logitech wireless laser mouse (MX1000) now for a little over a month and I've never been more pleased with any other mouse I've used. They use something called "fastRF" technology so I honestly can't tell that I'm even using a wireless mouse at all. Don't let the wireless part fool you. This thing is dead on accurate in every game I've played and every other application that I've used it on. I play games like BF'42, CS:S, HL2, DoomIII and the expansion, and others similar to it and it really is like night and day compared to any other mouse I've used. I've had multiple variations of the intellimouse and several different logitech mice before and was about to go with Razer Diamondback when I saw this one and I'm glad I did because it RAWKS. The only drawback with the laser mouse is the price........$79 is just too damned expensive for a mouse, even if it has a frikkin laser.
However if you're still cautious, Logitech's got a new gaming mouse out, the MX518 that is supposed to be pretty bad ***. It's got adjustable *in game* sensitivity and from what I've heard is dead on accurate also plus it's cheaper than the mx1000. Either way you can't go wrong.
