Hey y'all. I can't find a youtube video about where to place rubber bands on my uwell rafale subtank. I just want to make sure I've got them all in. So mine are on: the coil, both sides of the glass, and one is on the top of the middle piece (below the spit-back guard. I have a lot of extra rubber bands that came with the tank and I don't see a place for them. Am I missing any?
