I purchased this mouse from a computer fair, and wow, I never thought that I would have so many problems with a mouse. The mouse seemed to work fine until I shut down my computer. I wouldn't shut down. The mouse drivers were the problem. After removing them the computer shutdown. So if anyone is buying this mouse check the drivers throughly. Apart from that the mouse feels great to hold. The mouse wheel is a bit knotchy, but the buttons feel good. The overall design is very pleasing. And the customer support on the web is easy to find. Overall I would recommend this mouse to anyone who wants a wheel mouse with alow budget and a name they can trust.  Read the complete review
