I really like being able to make my own e-cig juice with concentrates. It's convenient, discreet, etc. I'm on my second device, however and the new one is leaking, too. The first one was a small box type deal and it leaked like a sive. This one is an Endura T20 and it leaks if I lay it on it's side. I hate the leaking, and the guy at the vape store said they all leak. I can't buy that! I want something that doesn't leak- I don't care if it is super adjustable or anything, just something the doesn't leak! Anyone have any suggestions?
