The Digiflavor Drop Solo is the latest game changing RDA designed by Brian from The Vapor Chronicles YouTube channel. The single coil 22mm version of the original 24mm DROP RDA, which has been widely recommended as the best RDA in the industry. 2 large post holes allowing for easy coil placement, and maximum build space with open access to trim excess. The post holes also have been designed with a notch to trap round wire builds with ease. It can take you into another level of vapour and flavour production.
