My Razer mouse’s primary button started going bad after about a year and a half of gaming (not professionally, evenings).

I took it apart and saw it was the switch assembly that just wore out.

My first computer was in 1992 and so I’ve seen quite a bit of mice in my time. That’s still the only manufacturer that’s failed at that level and I never purchased another.

It’s all marketing and overpriced in my opinion.
