My viper mini started scroll issue within 5 months or so, got it fixed and it happened again. Next time will directly go for the viper wireless or gpro wireless.
mine also start double clicking after a few month, but the scroll wheel is fine. i have a g304 that has a scroll wheel issue though, but its because i left it unused for a long time because the battery rusted the springs inside it.
i had a g203 and had no issues with it other than it double clicking a bit, but g203 and g102 seem similar so i'd assume it'd have somewhat near that build quality
Currently using a g102 for about 5 months now, I did notice my scroll wheel being bonkers last month but for some reason it went away and didn't do any fixes
Used it constantly for around 2 years, no scroll wheel issue, but double clicks on side buttons. Later on switched to the G Pro Wireless, and after putting away the G102 for a few months, the scroll wheel completely broke.
