So my Vamo kind of sucks at making connection with a lot of the stuff I have and I was thinking about replacing the o-ring. I noticed that my Kayfun Lite + clone from EHPro comes with an o-ring that looks like it might fit on my Vamo. It's the little black one that comes in the bag of extra o-rings and screws and stuff. Do you think it would work? I don't really feel like buying a huge bag of o-rings if I already have one at home. Has anyone tried this?
