The 22mm Drop Solo RDA by Digiflavor and The Vapor Chronicles is a unique follow-up to the hugely popular DROP RDA. The Drop Solo features a smaller deck with 2 raised posts set to the side, allowing the coil to easily be positioned in the centre of the deck, and for the legs to be trimmed after mounting. The stepped restriction allows you to customize the draw through the 10 airflow channels on each side of the cap, topped with a curved 810 drip tip. The deep well is great for dripping, or use the BF 510 pin for squonking. The PMMA cap include has a lower profile and fewer airflow channels, and focuses on flavor production.
