It will last about 3 years before failing. Usually, the clicky switches inside fail in relatively quick succession. Normally, I'd just swap that switch, but I'm all out of dead mice to harvest switches and LEDs from. However, the most recent failure was incredibly bizarre. I sneezed with the mouse in my hand and it quite literally simply fell apart in my hand. Upon review, it turns out the single post for the single screw holding it together snapped inside the mouse. In 35 years of mousing, that was the first time such a strange failure has occurred.
