got it guys. Constance, yes that's the tank. Bad attitude, got it. didn't watch the video, but can assume he was like me today with some expletives not deleted. This thing is not a travelling friendly gig. That's unfortunate too, I really like the flavor and vapor production. As soon as I got them today, I emailed my supplier, asked what the deal was, leaks, won't tighten. They emailed back, "unfortunately this is the nature of these tanks". I was ticked off pretty good, considering that it was my fault for buying them to begin with, buyer beware, due diligence and all that. I emailed them back, would be VERY helpful if you put the "unfortunate" statement in the description, instead of an email to me after I bought them. To the suppliers great credit, they suggested a "newer" locking version from the same manufacturer, sending one on the house. This supplier unlike many others out there, is wisely more interested in a long term customer than a short term sale. So here we go again, would be great if this newer version fixes the former's flaws. Thanks again guys, cheers.
