If one overlooks the fact that it is not silent (for those interested in such a thing) and that its LED is red (for those bothered by it), it is flawless and literally worth two or three times its price. Tremendous build quality and responsiveness, especially in the scroll wheel which is a key feature, very good ergonomics and comfort for a small mouse, perfectly accurate performance even on difficult surfaces, it also has an inertia function and an on/off switch. I don't think there is a reason to look at anything in a higher price range unless you have very specific needs, on the contrary, it is more likely that you won't come across something as good.
