First, to Mouse: works great, fits comfortably in your hand, no problems with Bluetooth.
The mouse sets actually after a short time (3s) sleep, but speaking again soon. In addition, the pointer not bounce. I do not mind this behavior. Incidentally, the Razer Pro Click Bluetooth mouse has exactly the same behavior.
However, I feel that you should be able to adjust the sleep interval. Otherwise you can also configure almost directly on the mouse all about the driver.
The second point of criticism concerns the operation via USB. Here it would be good if the inserted batteries would be loaded via the cable. If necessary, should simply be permanently installed and be recharged via USB a Lion battery.
Conclusion: Actually very good mouse, I will therefore reserve.
