You can choose the suitable e-cigarette tanks/atomizers in DeepVaping. For beginners, the sub-ohm tanks are easy to use and refill, while the experienced users will prefer the rebuildable tanks such as RDA/RTA/RDTA. The rebuildable tanks usually share high flexibility for coils and cottons. The bottom feeding atomizers provide a new way to fill the tank. Just get your own tank/atomizers!
