Good evening everyone, I am probably jumping the gun on this one with my vaping evolution but today I had attended a vape meet and i was introduced to a GG MOD,. I don't exactly remember the name pf it but it was the katana something or other. of course i googled GG MOD and located a GG at Clouds of Vapor. Does anyone know where i can get my hands on a GG? Are there other vendors that carry these GG's? or is it only clouds of vapor? I know startup costs for one of these PV's are high but i am fascinated with the fact that you can build your own coils. I definitely see the long term savings in these devices. Thanks in advance. Jason.
