I've had many mice, and I've never had one fail. I've got mice that are over 20 years old and still work.
So unless you are the hulk and not aware of it, I have to wonder if something else in your environment is affecting them.
Do you buy them all from the same retailer? Do you live underwater? Or next to a high power transmission station?!
Logitechs high end mice are lovely to use but garbage build quality. That little spring under left button gives out far too easily.
Its possible I click hard and certainly they got above average use but 3 died in 5 or 6 years
