I was disappointed in the proportions of the one I bought from dhgate (
http://www.dhgate.com/store/product...ass-vase-perc-water/175832535.html#st0-1-null). It took 12 days from order to delivery, so can't complain there. The glass quality is also good. I haven't looked at it with a magnifying glass, but at arm's length I see nothing that says cheap. But the can is smaller in diameter than my Ion (more so than I expected) and the mouthpiece/stem is larger. What were they thinking? With the water level just barely above the perc, using the EVO with it makes me feel like water is going to come all the way up into the vape. IMO big EVO and little bubbler is a bit of a mismatch. Even a nice easy draw creates an explosion of water. It's more of a psychological problem than a real one, but it makes me uneasy nontheless. It's a much better fit for smaller vapes with a more restrictive draw. If they had this design with Ion dimensions, I'd gladly pay 3 times as much and feel like I was still getting a great deal. I'm going to put in a buying request for bigger can and narrower mouthpiece. Hopefully somebody will realize different proportions will work better.
