I don't know what has to happen for this mouse to break. For the 7 years that I have it, I managed to finish school, go to university, finish university, get a job, find a girl, second, third, break up with them. It seems to me that even if hell freezes over, a meteorite flies into the planet or the universe collapses to the size of an atom, then this mouse will be the only thing that will not disappear anywhere and nothing will happen to it. Apparently, I will have to pass it on from generation to generation, because I am such a person that until a thing breaks, I will not buy a new one, and this device simply does not intend to fail, no matter what you do with it. In general, I recommend.
