I bought one of these as a back up, I can confirm everything CG said previous. For the price it's pretty well made. Most definitely looks like glass and even sounds like it, but is not.. I side by sided it with my kanger pro, and the draw hole in the top is smaller. I rewicked the evod style head with double over 2mm/32g kanthal I can definately feel it being a tighter draw, but works great and holds quite a bit more than my kanger, too. Overall, I would say anyone looking for a nice solid back up for non-hyperactive liquids it's tough to beat.
