On a Windows 7 sub-notebook tested. Simple USB nano receiver plug, wait until it is installed automatically, and then turn on the mouse. Quick and without any problems.
Handling
The weight of the mouse, as compared to a wired mouse, through the two supplied AAA batteries relatively high. That's technically but hard to get around and therefore typically as long as one has to rely on this common power source.
The size of the mouse is just enjoyable for my hand, but not necessarily suitable for larger hands. However, this is a subjective feeling.
Ideally, one mouse looks at from the outside that it is still switched on and not only signaled the LED that soon the battery dies would. So you can forget about it often.
The receiver is with me very quickly the mouse within one to two seconds after switching on. So far, he was not disturbed in spite of several wireless connections, the mouse responds properly.
No longer required to use a mouse and want it stored away, the USB receiver can really small store inside the mouse is very simple, so it can not be lost.
Reach
I tested it by about three meters. There were no dropouts or the like, so most users should be able to control your connected laptop to the TV unit.
Conclusion
Convincing performance, which should be quite sufficient for most users.
