Get a soldering iron and the other switches. Logitech uses the switches rated for a higher voltage which corrode over time. If they would use the correct switches, they wouldn't sell any mice anymore because they just wouldn't fail anymore.

Natural rubber isn't toxic to humans.
Synthetic Polymers are. I'm talking about the hard-shell and the lacquer that's coating the plastics.

It can be fixed by flattening the small copper contact inside the clicker or replacing it using one from a broken old mouse, as long as you know how and you are skillful enough to open the clicker and put everything in place again.

Place a thin piece of hard plastic paper cut in the right shape inside the wheel encoder to increase the pressure just a little so it doesn't jitter but is not hard to roll.

This was an interesting theory on why they fail.
I ordered new omron switches, i have to replace them every year.
What I should do is come up with an optical or magnetic replacement, but the switch is pretty small so it makes it a bit difficult.
It might be worth while to come up with a “de-bouncer” to get rid of the extra click if it’s within a few milliseconds.
Although, thinking about it now, this could be done in software.
My G403 still works perfectly after 5-6 years and I played Minecraft 1.8.9 PvP (clicking 10+ CPS for extended periods of time) for like half of that time. I don't understand what you spergs do to your mice.
I still keep it around as an extra 'work from home' mouse cause when I balance the laser/led/sensor just at the edge of a cd jewel case, it acts as an undetecable mouse jiggler and my cursor moves on it's own.
