I'm just stating my opinion. And if you read the whole thing. It's just just a leaking problem. The cups them self makes a lot of clunking noise. The leak it's from the solenoid. If you wanna buy its I don't give less of a s**t

And gene too late hahah he already did lmfao

I've got mine air cup suspension from Stanceparts | Air cup lift system
I must say that I really am 100% satisfied, the quality is really good.
So I don't agree with your opinion, However, I use air cups of stanceparts.. so it's a bit different. I'm using it for 3 years now, never had problems... and still use it with every ride!
