First I'd like to say that Eciiggity is one of the top Vape stores on the net. Really fast delivery. Three days regular mail from the Islands to Chicago. Great site for finding retro tanks like this one. This RTA is a good DL (not so much MTL) It's a little fussy. Gotta make sure everything is screwed tight & if you don't get your wick right, it will leak. Once you get past the learning curve, it hits like a champ! I bought it for my 22mm EhPro Tube mod. Travels well.
