Ok, so you're somewhat of an vape veteran now. You've been using your regulated mod for some time, have moved into the variable voltage world and may even have delved into the rebuildable atomizer world.
Well next up in the quest for the best flavour and vapor is mechanical mods. These mods are for the veterans as they are unregulated meaning extreme care must be taken when using them. So do you research, know your ohms law and come back and find unparalleled flavour waiting for you.
