Special thanks to Logitech for their attentiveness and the presence of batteries in the kit. It really is a Plug&Play product. Additionally, I will add: one of the reasons for changing the mouse was the incorrect operation of the previous one. For some unknown reason, when even a slight pressure on the mouse was accidentally pressed (pressed into the carpet), the sensor stopped reading and the mouse could completely stop on the screen when it was physically moved over the carpet. This was not the case with the second available mouse. The new mouse works perfectly, no such problems are observed. Works great on existing surfaces (carpet and painted table).
