Good mouse with nervigem standby behavior

The mouse itself I really like, it looks despite the black piano lacquer surface from quite nice, has a nice feel and is suitable despite the small size also for large hands.
Under Ubuntu 4.12 it was available to me also readily prepares Windows has a few problems, but this may well be my Bluetooth hardware.

Unfortunately, the mouse has the annoying property to imagine you are in about 2 minutes without moving in a kind of sleep mode, so it does not react with the next movement for a few seconds. Since I rarely use the mouse and much work with the keyboard, that happens all the time. Anyone who works mainly with the mouse, is hardly disturbing.
