I don't understand how Logitech mice are so popular given how frequently they fail due to switch problems.
Everyone I know, from casual users to gamers, has had problems with logitech mouse button failures. Sometimes within months of purchase, even on their high end gaming mice that cost well north of $100, the buttons will stop working or start double-clicking.
I've had multiple buttons fail on my Logitech mice. It is an issue, even if not everyone experiences it. (And yet I still buy them because they have some of the best ergonomics and buttons layouts I've found in wireless mice.)
The switches "plague" is a very well known issue [0] and it's not reassuring for any potential buyer as you have to return affected devices eventually, DIY replace the switches or hope contact cleaning spray keeps the problem at bay. Despite knowing this I still got an Ergo because, like another poster said, there really wasn't anything like it I found as comfortable (and the many 3D-printable ad hoc designs for further, extreme inclinations were a big incentive).
That's the cheaper Chinese Omron switches.
They are complete rubbish for the price point, in a Logitech mouse, as you can't easily swap them out.
Asus are now selling mice with hot swappable switches. I made the (sorry) switch myself after my G903 died, ie I couldn't hold the buttons steady.
I see now that I should be able to source Japanese Omron switches that might be a bit better; the replacement in the G903 requires some patience and (to be developed in my case) skill, but it's not like I can break it any further. Will grab extra spares for my Chakram X at the same time.
I have not had button trouble, but they do just drop dead about every year or two. Corpses are piling up. I even try changing out the battery before I give up on it. That worked, once!
Their Unify dongle usually has to be at the end of a USB extension cable for it to work at all, for me. I don't even try it without, anymore.
Do their failure rates reflect some sort of massive deviation from the rest of the mice on the market? Given that most of the high end mice use the same switch manufacturers I'd guess it's more likely that you see more instances of people complaining about it online because they're vastly more popular than other mice manufacturers.
Interesting. This isn't to argue against that experience, but I still have and regularly use a wireless Logitech mouse that's at least around a decade old. I had my previous one for years in daily use as well, although I can't remember how it failed or why I replaced it.
I wonder if they've changed something about the buttons.
personally it's because logitech is the only mouse that can store their custom mouse bindings and DPI onboard. every other mouse needs to have a daemon running constantly on the computer in the background for some reason, and that's a no-go for esports
