He took some time to synchronize with Windows 7 but that's Windows 7 that takes a long time to install the necessary drivers (A little annoying sync after a while). The keys are right for me, the touchpad responds well, the laser will be good for a presentation. On Android, recognized directly on my tablet and my Samsung phone (101 and Ace Note 3). Key on Android, bad because the key must be slow (1,42GHz instead of promised 1.8GHz) keys annoying repetitions, imprecise touchpad, TOP not for navigation on this key.
