First, I must confess: my Microsoft mouse is now in the dustbin. The left button was broken - which indeed can be disturbing since. Nevertheless, I can fully recommend to buy this product. Because the disorder is the result of about 12 years of use of the device, and that's saying something. She is very good in the hand, the cable has a proper length, it works quickly and accurately, is also suitable for playing, the buttons are easily accessible - but hard enough to push that you can not ever accidentally triggers undesired operation. Therefore, I have now been re-appointed :-)
