Also convenient is that the mouse realizes with which device the mouse was connected the last time. Unfortunately, she remembers only the last device and not the final 2-3, so that the coupling has to be done yet.
Something unusual is the standby behavior. After a few minutes the mouse "from" what I would not describe as uncomfortable going.
Once briefly turned on the scroll wheel or clicked and already it is reconnected to the terminal, whether Androidtablet or PC.
Although only 2.1 BT used instead of the power-saving 4.0 BT seems the power consumption is not to be particularly high. Since 3 months she is now with me with the included Duracell batteries in operation and the tension has decreased only slightly. I guess they make a further 3 months before they make limp.
From the ergonomics is not bad, only for people with very big hands and this mobile mouse is nothing. Even the sliding behavior is very convincing.
The included transport box is small and protects the mouse from knocks by foam around.
