Summary: Like all the other reviews here this mouse is really good!. Convenient, well designed and a traditional mouse is much quicker than using the traditional track pad on a laptop. The price isn't bad either!
Summary: Overall, this is an excellent product. The buttons have a good 'click' to them, it's very responsive, and it literally works on every surface (even glass tables). I'm constantly relocating, so having this small, wireless mouse is very convenient. My only complaint is that the scroll wheel is a bit loud. I work in small teams with my coworkers so it's something I'm a bit self-conscious about it, but it hasn't seemed to bother them too much.
Summary: Tracks ok, suffers on slick or reflective surface, I personally like my weighted gaming mouse on my desktop but these work fine for portable use. Decent battery life too even if don't turn them off, and the dongle is low profile.
