: On the advice under my review, I bought an extension cord for a bluetooth transmitter, now it is 20 cm from the mouse itself, there are no more problems with signal loss, everything works as well as possible. With its pros: Very rich equipment, they also put pads for the legs, if the old ones are worn out, the side buttons (of different colors and they can be changed), even switches for the main buttons + all sorts of stickers. The mouse is very light, pleasant to the touch, the buttons all respond well. Even the included charging cable is excellent. The mouse holds a charge of about a week when used 5-6 hours a day, sometimes even more. With its cons: I donโt know how this happens, but from time to time, because of the signal, it starts to lag, or rather the cursor itself starts to twitch, I canโt say why itโs connected, but it goes away very quickly and not every day, such a glitch is possible every 3-4 day.
