Great for the office, this mouse is precise, comfortable (much better than a mini!), Light, it glides well and the wheel is slightly notched ... The cable is long enough and handy USB port. Easy to install (no installation cd). To have purchased other much more expensive, it is very responsive and works well, despite two or three drops in 6 months. In short, a good quality / price ratio.
June 2015: it has been running for 4 years without any problems, several hours a day ... I am completely satisfied.
