I've used this mouse heavily for about 4 years. This is definitely a mouse that you put your palm on. There's a decent polling rate such that you can give a quick swipe without having the cursor hang. Compared to wired gaming mice it's not the best but this is the best wireless mouse I've tried for fps gaming. Since the wheel is "smooth" scrolling if you press the middle button sometimes it scrolls a tad. Sucks to zoom in with sniper rifle and then suddenly switch weapons. But this happens with regular mice too, just a lesser extent.Of note you may have to position the wireless receiver in a few places before you get perfect signal. Also since the polling rate is so high the battery life isn't the best. I use only one nimh battery in the mouse and it lasts for a month (8 hours a day). You could use two batteries if you'd like but it's too heavy for my taste.
