So....since I last posted I have tried the Vivi Nova 2.5, the Mini Vivi Nova, the Mini Submarine Tank from Mom and Pop Vapor Shop, the J-Tank, the Stardust clearomizer, and the E1 ReLoad from GotVapes. I wanted to like the Vivi's, but the taste was there in the beginning, then tapered off and I gave up on them. The same goes for the Stardust and the E1 ReLoad. I have had the best luck with the J-Tank, and I made the USMC JonBoy LavaTank list this time around, so I am waiting to be picked out of a hat and get an email about that.. The SmokTech DTC absolutely sucked. It leaked everywhere after awhile, and I have no patience for clean up all day long. And who wants to re-wire their own coils? Not me. The idea is great, but until they make the thing useable right out the box, I don't want to try it again. I will try a couple more tanks before I spend the loot on a glass tank, but I think carto tanks are the way to go for me, YMMV. All this is IMO. I have a tank tool, and it makes for ease of re-filling, and I love the taste..(oh, and I'm using 50/50 juice, because I don't care about throat hit, and I want to throw clouds of vapor in the air..
