The mouse has been working for me for more than 3 years, but it's a bit dirty and I cleaned it. The reason for selling is that it used to freeze suddenly all the time, but I tried it a little while ago and it was acceptable. The RGB in it is broken, but it's not a problem. The button in the middle sets the speed level (DPI) to each color. Price is 50, negotiable. Whoever wants to talk to me on WhatsApp, I am at the authority.
