I received my second RMA'd mouse back in January, I think. I'm on my third one since June 2019.
Here I am, three months later, same problem.
Sad to say the switches in these are just not up to snuff. The thing feels great, but I get an exceedingly longer lifespan(years) out of a cheap mouse in comparison. Three to four months is as long as each of these has lasted.
I'm hoping they will have a revised model this time, with better switches as I don't really want to keep having to RMA it.
