IME the thing that tends to fail with mice/trackballs is the snap switches used to actuate the mouse buttons. They have a lifetime, and once they do they start to glitch.
But if you know how to solder sometimes you can replace them with better ones. I've been a heavy user of the Logitech M570 trackballs that are notorious for the poor switches they used that would fail after 2-3 years' of use. For the last batch I bought, I replaced all the switches with some high quality Cherry switches before putting them into use and had them last about 10 years before the electronics started to fail.
Once they died I replaced them with some cheapo Chinese wired trackballs since Logitech doesn't make wired ergonomic trackballs anymore: we'll see how they do and if/when they fail whether the switches can be easily replaced.
I do like my high DPI Logitech gaming mouse, though I don't like how hair-trigger the buttons on it are. I suspect the switches on that thing won't last very long, but I don't use it much since I tend to play games on Controller.
There's also a particular mouse model I came across a few years ago that's designed to have a setup for super easy Omron switch replacement. I think it was Asus. Here's one model that has what I'm remembering.
