Who Uses The Drag H40? Because The "PRO" is "PRO"

3 years between the H40 and the H40 Pro is still kinda blowing my mind. That long between releases is unheard of for China. With that said, this is some high quality RDL / MTL vaping. The PNPX coil heads have pretty much proven themselves to me at this point. I prefer rebuilding for the crackle sensation, but this flavor is top tier. VOOPOO... RBA!!
