This lightweight device is activated by drawing on the mouthpiece. The pods easily slide into the top of the battery and are held in place by magnets, so no need to worry about threading issues. This makes DOT PRO an ideal starter kit for new customers trying to switch from smoking who want a simple to use device. The DOT PRO Pods contain nicotine salt, which is a variation of nicotine traditionally found in e-liquids. This creates a smoother vape for the higher strength of e-liquid. DOT PRO Pods come in 20mg/ml strength and seven different flavours. Please note: The new DOT PRO is NOT compatible with the existing DOT products.
