I have two Wireless Pro Gs, one for work and one for home. I used a g502 for many years and the battery started being shitty with it. I replaced it, but it kept telling me to change it anyway. I then got a g502s that failed within 2 years with double clicking. Then a g902 I think, which started double clicking just after a year. Then I got my first Pro G. I enjoyed it enough to fork out for a second one for work. A couple of months ago, my at home Pro G started double clicking, this is maybe 2-3 years in now. Blowing it out helped a little, but not much. One time I accidentally opened a whole bunch of emails I was going to delete, and slammed it on my desk, and it’s been fine since.
My next mouse will probably be a different brand, even just to play the field a bit.
