Squonk mod with a 20700 is amazing. Basic and easy to use. Mod gets 5 stars. rda gets 2 stars. While may be a decent cloud chasing rda, the flavor is muted harshly and this mod can't handle 2 coils for long with just 1 battery. I got the WOTOFO Recurve single coil srda and never looked back. This rda that's part of the kit is somewhere in my floorboards of my truck.
