Summary: This seemed like a good, cheapish small mouse to replace my old Nexons mouse which finally gave up after several years. This one looks good, is small and easily stored in laptop bag or moved around. However, after only 2 weeks, it has gone hypersensitive.
Summary: Very small and light. Doesn't feel terribly good in terms of build quality. The scroll wheel is a little stiff, as is the middle button, and the default sensitivity is ridiculously fast - you'll need to turn it down a notch in your OS settings. However it works fine, and I'm generally happy with it.
