The Vandy Vape PHOBIA RDA delivers a quality-machining 24mm rebuildable dripper with a postless-like design with four terminal posts for vertical installation and a unique dual airflow design. Measuring 24mm in diameter, the PHOBIA RDA is constructed with the superior design elements Vandy Vape has come to known for. The sturdy Stainless Steel shell is highly durable and the PHOBIA 24mm RDA utilizes a gold-plated M4 Hex Screws for added durability. The build deck sections features four open terminals, in which coil leads are vertically installed onto the base and side-secured for easy installations. Airflow enters the structure through dual bottom airslots, redirecting to a two-direction airflow from the bottom and the side to create a cyclonic vapor production. The PHOBIA RDA uses a custom 810 ULTEM Chuff Caps along with the ability to be used with other 810 drip tips. Also included in each kit is a squonk 510 pin to be used with squonking devices for added versatility.
