My setup of choice involves 808 cartomizers connected to 510 power (eGo or mod) via a thread adapter (from madvapes, if I recall). One of the reasons I prefer this kind of setup is the slightly tighter, more cigarette-like, draw the adapter introduces. What I don't like about it, however, is the difficulty I often run into unscrewing the adapter from the battery end to charge the eGo battery or clean the connection on my box mod. Sometimes I have to use a pliers and other times I can get a good enough grip by wrapping a condom cap around it. Has anybody here worked out a better trick for unscrewing these adapters? Has anybody come out with one that's knurled for a better grip?
