Both my MX-M3 and M705 mouses are lagging behind. Must switch between them all the time, can work for about 3 minutes, then I have to switch to one or the other for 3 minutes (and it is one on a good day) and so on. The MXm3 is an expensive device so my disappointment is as great as the price. checked YT and there seem to be more than me who are disappointed. Had to buy something that works so I bought a Chinese copy (Rapoo MT750S) that works perfectly. What is wrong with the products? I work in Windows 10 and catalina 10,15,7 and the mouses do not work in any of the environments.

Sincerely
