Similarly, even the higher-priced Logitech mice often use tact switches that are only rated for a relatively low number of clicks (probably 1 million?), so many of them started failing on me after about two years. Replacing the switches with higher-rated ones (50 million clicks) is trivial on all the mice I have disassembled so far. The switches and replacement glider pads (which need replacing after removing the screws hidden below them) are often just a few bucks but make the mouse last for several more years.
I've done this fix on at least 3 MX Masters, just going in through the rubber on the side to remove the switch, since disassembly through unscrewing everything is more work.
Needing to replace the feet every time you open the mouse is pretty frustrating.
I feel you. Here in Europe you have to pay around 100 bucks or more to get some decent quality from Logitech. In the past I used mice like the G9 which was build like a tank. Nowadays it's something like a throwawy part, even in the higher price range. Same goes for keyboards, which I tend to build now on own.
Yes, I no longer pay extra money for Logitech. If the quality is as bad as a cheap offbrand from China, why wouldn't I pay less for the cheap offbrand?
I'm glad to pay for quality, but Logitech no longer seems to offer good quality.
Personally speaking: I could not find anything that would be a match in terms of quality and ergonomics for the MX Vertical. Tried a small number of cheap vertical mice, none of them felt right.
