RDA's (Rebuildable Dripping Atomizers)
For those serious about their vape, the RDA is probably one of the best options for the hardcore vaper.
RDA's are intended for experienced users only. They are for users that wish to create their own custom coils. These atomizers can be assembled over and over using wick and wire. RDA's do not work right "out of the box" and require assembly. The performance of a rebuildable atomizer is partially dependant on how well the user assembles the wick and wire.
