I'll make it short times, the mouse is who you play with matches, I find very good. But under Windows 7 wen I read through texts where you have to scroll whether Office, Word or on the internet, it scrolls just saying a few lines, which is sometimes very annoying. That's why I prefer times from 1 star, otherwise there are been full 5. Do not know if maybe I have only the problem? But who someone knows a solution, they may like to tell me, I would be very grateful for. Otherwise, it is as written above, very good.
