Conclusion: I tried it on Windows 7 pro SP1, 64 Bit As others have said, when it goes dormant, it no longer responds. Double left click does not reactivate.
Pros: works well when connected, switching between calc and keypad is well thought, accurate movement and glides well
Cons: it's essentially a paperweight it's so useless, fails bluetooth connectivity miserably, out of the box it is over responsive
Conclusion: - in case you have no Num Pad it enables a quicker numerical data entry - connectivity and instalation under Windows 7 OK, quick - i would welcome more functional keys
Pros: good idea, good built quality, lcd display for offline calculations
Cons: more functional buttons would be great, the white color on the keys is a little dark, not able to program the buttons for other functs.
Conclusion: I've been trying to connect the mouse for most of the morning to my Win7 laptop. The computer shows that the mouse is connected but cannon populate any of the device info...
Pros: it was a nice idea
Cons: will not connect to computer, calc/kp button does not work, feels very cheaply made
Summary: It functions as expected although I would have liked an ''off'' switch. It is comfortable enough for light use but the size might make it awkward for small hands.
Summary: Usually people do not read a Manuals ;-) That why "Connection failed" after few hours. The mouse has sleep mode after some inactive minutes to save battery energy.
