Uh, what would I be paying for, exactly? I don't really see what Software support a mouse really needs, as long as it doesn't ship buggy. Also, I've been using my (Logitech, funnily) mouse for 6 years now, and if you ignore the few scratches it has gathered, it still works pretty much perfectly.
Also, if their solution for a longer lasting mouse really is repairability, isn't that just their way of saying "we designed our other products to be thrown away"?
You've had more luck than us. My wife went through two Logitech G305s in like 2 years, so I switched her to a Razor DeathAddr and she's been much happier.
At work, I use macOS so I went with MX Master 3 and had constant issues with the thumb button not working. It's better now (I guess their SW improved?), and ironically I had far fewer issues with my Triathlon (when I WFH), which is much cheaper.
On my personal devices (Linux), I use Microsoft Intellimouse Pro. It has been solid for over 5 years. I plugged it in and it just works. The only thing remarkable about it is how little I think about it, it clicks, scrolls, and reads input consistently. If Logitech could do that, I'd probably buy more of their stuff, but I've mostly had issues.
It's a MX Master 2S, funnily enough. I still have a over 10 year old working M705 Marathon, on second thought, that I had once bought for my laptop. Had to open it up and bend the mechanism for the left click back into shape once, but no Problems besides.
