It's funny how these 'vape' companies work. I ordered a battery for my 'BUD' Cartomizer. One would think they would include some info on what else I might need but no. Can Someone Please tell me the name of the third stupid piece I need, I have 1) Battery and 2) Cartomizer, now the cartomizer is all unprotected, what is the piece that would screw onto the battery covering the cartomizer? Do I have to start a whole hew thread for a small question like that? I hope I never find companies hard to deal with as these 'gotvape' companies seem to be. One would almost think they are Smoking Something to be so non-professional. ;~) (Not Tetralabs they're great) otherwise, Worst Industry Ever.
