I used the mouse regularly for over six months, maybe a little less, and it worked for everyone, but then it started to shut off constantly. It later turned out that the problem was with my USB ports, but I changed the mouse nevertheless. Most importantly, I didn't like how dirty it got; dirt went into all the gaps, especially in those pitiful holes on the left, and I got tired of using a toothpick to clean them. Naturally, as a CSGO player, I was aware of the lengthy response time. Heaven and earth after switching to Bloody V7. Generally speaking, if you truly don't want to spend money, that's it, and everyone is well aware that x7 is a good product for not spending much money.
