Just received my Vamo v3 last week (up till now been using Egos for 5 months). I love the Vamo when it works, however the problem I am having is that since there are no threads holding the battery tube to the atomizer, the battery part is sloppily loose causing it to not make contact or at other times just fall off. I use it almost exclusively with the short 18350 batteries both flat and button top, not stacked. I am mystified that there is no way to snug this connection up like a luer lock or threads. Is there anyway to fix this issue? Thanks!!!!
