After Amazon, most reviews are clearly positive, I thought that this mouse may very well serve as a cheap replacement mouse. But unfortunately she is no use for it. This is due to 2 things: 1 in that it and the cable is extremely light quite tight, it moves by itself when you let go. 2. and that's far worse: on both PCs where I've tried it, freezes the Windows Explorer (+ Taskbar) once I plug in (both Windows 7)
