I received my pre order 2.0 over the weekend. Got to say I am really impressed with the improvements. The change to the air intake path has greatly improves on the draw. 2.0 does a better job of maintaining the selected temperature regardless of the draw speed. The unit itself finish has change. More a matte over the OG being more smooth. Much easier to hold onto too than the OG. Haven't had a whole lot of time to play with unit but battery life seems to have improved over the OG. Really been impressed with my OG over the last couple of years. I feel the 2.0 has improved upon a already great product. Price may seem high but when you take in account of a lifetime warranty great CS and it's made in America for something made of to last, it's really not that bad. With the fc discount even better.
