You never mentioned what the pen was hitting at with the volts, and mah rating this battery has.Well from my research of the product it is basically the same as a standard non sub ohm atomizer. It even uses organic cotton. Regardless of the nicotine level it's just not very good in my opinion. I simply believe if they want to do that style of product then give me more options. Refillable tanks. Something. The cost is simply too high for the product in my opinion.
