Value for money: 2 / 5
I rated it a 5/5 because it's a great mouse with rediculous range and great features. The battery lasts a long time and the usb dongle fits in the mouse makin it great for notebooks.
But it has a material quality flaw. The rubber "comfort grip" stretches and causes the scroll wheel to stick, making it very difficult to move.
If you have this mouse check out logitechs forum for an easy fix.
