Vandy Vape have released the Bonza BF (bottom fed) RDA which allows you to use this RDA with a squonking mod. This product was created in collaboration with an Australian Youtube reviewer " The Vaping Bogan". The idea is to ensure that the deck is easy to build on with fixed screw clamp posts. Supporting both single and dual coil configurations, this is a 24mm diameter RDA with 3 colourful food grade resin drip tips - Yellow, green and red. E-liquid will saturate the cotton from "down under" due to the hollowed out 510 pin.
