"HORRID...Do Not Buy!"1.0 starson by Chaos-Katie
Pros: Nice design, cool fold up feature, and sleek looking
Cons: Awful functionality...jumpy and shaky.
Summary: Absolutely horrible on a functionality level, sporadic scrolling, shaky and jumpy, sometimes wouldn't connect to USB. I really liked the design, fits hand well, folds up so it's good for on the go (was the reason for purchasing it in the first place). After a month and a half I finally went out and purchased a $20 wireless Targus and has worked great. This mouse was the first Microsoft mouse I have purchased and would be the last. Don't buy, it really is a bad purchase. I found similar reviews on Best Buy as well.
