Query: I love this mouse

This was the first trackball mouse I ever tried. Man, I love it. It works so well, and it's so easy to clean (you just pull the ball out and clean the little wheels and such). It feels very comfortable in my hand. It's thanks to this that I'm now a bit clumsier with a regular mouse (I'm not good enough with the trackball for FPS games and I'm definitely no good with a regular mouse anymore) since I don't use a regular mouse anymore if I don't have to.I'd definitely recommend this for trackball lovers or for anyone that wants to try it for the first time.
