With this mouse here I found it. The shipment was quite fast and the mouse was safely packed. The first impression was really positive, the processing was better than expected and all keys could be good press. The right and left mouse buttons have a soft but pleasant pressure point. The scroll wheel is smooth and has good catch levels.
It is good that just a battery case is to take the mouse in operation. So I have the receiver plugged into my mini PC and then I was able to use the mouse. The transmission is stable even at a distance of 5 meters and thus exactly what I was looking for. I would highly recommend it.
