Ok, so I've been vaping RBAs for about 2 1/2 years. At one point in time I was up on every single new thing that came out or was going to come out. Though the last 6 months or so, I've been out of the loop following new products and I've missed alot. Aparently the tanks that use pre built coils have come a long way. The last one I used was a vivi nova tank over two years ago, which was lacking in many ways, but was the best that was offered at the time. I've been wanting to pick up a pro tank or aspire or something to pair with an iStick, but didnt want to waste money on something that I wasnt going to be happy with. So I'm hoping one of you guys can point me in the right direction. I really appreciate any input. Thanks.
