They say they have changed the more complex steam path and fix the closure problem ...Let us know what you think if you get one, seems this is a NEWER V2 version. The original did not get very good reviews from Troy (420vapezone), and a few other reviews I read. Costly, rough fit, no appreciable cooling difference, was what I remember, so I passed. Maybe new model addressed those issues?
In 1 or 2 months I will buy it, I would say my report on the forum.
