Hello everyone. Definately a newbie here. I bought the Fifty one "DUO" here in virginia beach and PAPA JOES smoke shop. They have been great. Great recommendations and very easy to work with. I thought that i had screwed something up. The first set i got nothing out of. The second set, the Atomized Refill filters, i thought was bad, 10 of them, but i read a post from "MAC" about unscrewing them 1/4 turn, and now they work great. Still wish i could get more vape. Any suggestions on where to go from here? Any and all help would be greatly appreciated. Thank you in advance.
