At first everything worked fine, then I changed the router and there were problems with the signal. I thought there was a problem with the mouse, I wrote to the seller and he, as I can say, was very adequate. He answered all the questions and helped solve the problem. However, this was not a news for me, since I previously bought a keyboard here (k500-b94, excellent keyboard) and the seller always responded to my messages and helped. The mouse is excellent, the shape for the male is perfect (like the old a4tech x7 or Razer deathadder). The simplest thing, in Russian, is that even the child will not have any problems. It’s not very pleasant to hold bare plastic, so I ordered rubber stickers for 120 rubles, it became convenient + the hand sweats less. I disassembled the mouse and weighed it up, there is a special place for грузин, you can see if you disassemble it. Crch, if you are not as stupid as I am, then the mouse is fire.))) Good shopping to everyone. The monic is also from this company, if someone is interested in the MK32QG165S2RU.
