I've been rebuilding for quite awhile now. It all started with wanting to be self sufficient during the end times. I watched tons of videos, read all I could, then dove in. My first was the zenesis standard that arrived totally setup, ready to vape. That made it so easy to fully understand what I had seen & read. Next, I dove head first into the entire MMVapors DID series, beginning with the largest at the time D-20 which is quite roomy for setting up. Since then I've aquired RDA's too, and a Richman atty. The easiest to set up of all so far, was the Richman, when it comes to knuckles and eyes, but the DID 20 is only a smidgen less easy but provides better vapor & flavor. MMVapors I
Has just released a D-22 which looks like the easiest of them all, plus easiest to refill.
So many Genny's, so little time...
Good luck in your venture!
