I had to replace it with competitor 105 because the "wheel" button had stopped working, but with sensei ten it began acting up the encoder very quickly (about a month or two later), which is why it began to mistakenly detect the scroll'a movement up and down. In my quest to find a remedy to the issue, I came across it on a video in which the encoder was soldered, along with the purchase of a component from China; however, this is, regrettably, only a temporary reprieve from what is ultimately going to happen. As for the body, there is a significant issue with the strength. If such a misfortune occurs and you are forced to disassemble the mouse, then you should be prepared to dance with a tambourine: there is a high probability that the thread will fly off immediately due to the poor quality of the plastic, and you will probably not be able to screw the screw back in, so you should come up with something as a countermeasure, such as making an impromptu carving out of epoxy or something along those lines. In that case, I will make an effort to ensure that I do not forget to add a review. I really hope that this flaw is nothing more than a flaw.
