"This brand new mouse is really a good buy due to its reasonable price. We
tested it for days and it really works great. The most amazing thing is that
this mouse is as accurate as any other Microsoft mice. Thanks to the digital
radio technology that the mouse used! As it used two digital channels you can
also used a second radio mouse on the same computer."
