The SMPL Mod Clone by Wotofo (A-Mod) is a compact mod that accepts an 18650 battery. It has direct battery connection to the atomizer for minimum voltage drop. The body is all one piece and the battery must be removed from the bottom cap that is also the spring switch. The Black Color is made out of brass with a black rubbery/matte texture wrap on it. If you’re looking for a clean, short, and simple mod, this one is for you!
