The Sub Ohm Innovations SZX Competition RDA is a cloud chaser’s dream, featuring massive airflow and a monstrous two-post build deck. Huge post holes and a high pressure clamp system make big builds a breeze to install. 8 large airflow holes with top-cap airflow adjustment allow you to hone in on the perfect draw, airy or restricted. A large protruding 510 connector makes this RDA safe to use on most any hybrid mod, and pairs perfectly with SOI Sub Zero mechanical mods. The 510 connector at the bottom can be removed from the RDA to enable a true hybrid connection when threaded directly onto the Sub Zero X or ShortyX mechanical mods.
