I'm using my Elecom Deft Pro trackball right now and while it's nice it doesn't come close to feeling like the quality that my Logitech trackball feels.
That's exactly why you don't experience issues, your devices don't spend enough time getting clogged with sweat, oil, dry skin and dirt.
All of my gamer friends use Logitech to the max of their abilities, and almost all have experienced issues with their products. We're from a poor country, originally, so we only change the gear when it's absolutely needed.
Personally, I only recently retired my old MX518 bought in 2005 and I had to rewire it twice in 25 years, the USB cable fractured each time, but the mouse itself was flawless until, 25 years later, the MOUSE3 button stopped working.
I like the idea of having repair guides for devices, to fiddle less when self repairing. I'd expect fewer negative reviews once these guides get published.
What's more interesting is how well the product works after 3~5 years. I had a few Logitech mice which worked fine, but i.e. had a matte rubber coating which inevitably dissolves and gets sticky after a few years...
Why?
My oldest actively used mice in my household are two decades old, variations of Intellimouse.
My razer death adder was a luxury / whim purchase and is 5 years old I think.
My daily workers are ms skulpt and they're several years old each too.
(and let's not go to keyboards, where the original das keyboard and original MS ergonomic hold the fort still :).
And my Kensington trackball is at least 20y now and still works as new. I do have a razer Lachesis whose rubber started melting so I just sanded it off and back in service :)
I do have a friend who keeps buying mice but he never quite managed to explain why, other than "shiny - want!" (which is totally understandable! :), so I wonder if you have more specific criteria or needs? Am I missing out on something?
(I did buy a fancy many button Logitech once but the clutch scroll was such a massive and immediate Nope to me, it still sits in its box in the drawer :-)
Other years they don't really update anything but the looks, I skip over those. I've had some logitechs for 3+ years that wind up as my travel mice, etc.
But about half of them died within 15-16 months. And by "died" I mean, 1 click became either 0 (bad) or 2 (much much worse!).
None died within the 1-year warranty period, though. So that matches your experience. And the mice are so good I was almost OK with that, but not with more than 1-2 mice.
So then I bought a shitload of non-logitech mice, but.. it's hard. Ignoring the awful software and premature mechanical degradation, there really aren't better mice. I ended up with mostly ASUS ROG Chakram (good, but laughable charging flaws) and Razer Basilisk 3 Pro (good, but not good enough for the insane price; costs more than my first car).
Does the receipt track the serial number?
I also do this with e.g. camera batteries, vacuum batteries... basically anything that costs more than $50.
The thing that has only recently made me swear off them is their utter hostility to Linux support. Now I don't want their software, but I expect when I buy a mouse I can at least get the hardware working in Linux, but no dice..
So no more Logitech mice.
Likely you are not using the mouses heavily. I had many die on me. Especially my sweet, sweet G500 - the best mouse ever for people with large hands - actual large hands, that is. I repaired the clicker a few times by soldering in new clickers I bought online, but they wear off too fast.
Before that was a Deathadder, also button failure. The only mouse I've replaced for any other reason was a Corsair M60 which had its cord chewed off by a friend's rabbit. We soldered it back together but it didn't last.
Now on a Razer Basilisk Ultimate which uses some sort of optical click detection, we'll see if that's actually more durable or not. There's still a physical mechanism to produce the clickiness but I don't know if that part is failure prone like the mechanical buttons have been.
