The Dripper RDA is exactly what you think it is: a rebuildable dripper. This is a very basic design, perfect for someone who wants to get into rebuilding. There's a 1 positive and 1 ground post, ideal for single-coil builds. Airflow has been improved over past RDAs, in that the airflow comes in from a hole in the side, instead of at the bottom of the deck. This also means reduced leaking. The top cap also features an integrated mouthpiece for a uniform look. The Dripper comes with a pre-made 1.8-ohm coil, but really shines when rebuilt with your own wick and wire.
