Your adapter must be crazy-short! My 510-510 adapter is probably over an inch long! I seem to be having the opposite problem to you. The stardust sticks up out of my mini like crazy. This and the draw is way too airy for me as the adapter has holes too, effectively doubling the air I'm able to suck in! I'm guessing the perfect adapter is sold on Provape's website, which sucks because I failed to anticipate this problem and order one. Trying to locate the correct adapter from a supplier in Canada right now....
