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.
Summary: Having had a similar Trust mouse for six years,which is still working fine, I had no doubts this one would be good quality too. It is comfortable to use;responds very quick, and has a handy up and down page scroll facility, which you activate by pressing down on the centre wheel.
The roller ball has just broken after only 3 months of use.

Summary: I was very happy with this as a mouse, until now. The roller/slider that I use to scroll up and down a page has just died on me. This has suddenly become quite an expensive item for just 3 months of use. Very disappointing.
