Nah, I deployed Logitech for ~300 users in a manufacturing environment for years and they were just fine. You got unlucky or are beating the shit out of them.
I won’t claim to be a statistically representative sample, but from my experience their high-end stuff is expected to break after between 2 to 3 years. I kept going back to them because the hardware is very nice when it works. I gave up and bought a Razer Naga about 3 years ago. Hopefully it fares better in the long run.
They're mostly M100(?) mice from the MK120 combos. They basically all start doubleclicking eventually.
They're not all from my personal computer though, probably from about 8 different PCs.
