Aslo consider the Kgo, E Power (with replaceable
batteries) and the X2 (which dos provides a pass
through feature)
Yes, I love my Kgo!! It works great with the ego visions, and I have never gotten a burnt taste off of it.
I got mine from Sweet-Vapes, pretty good price, and they have a kit that comes with Ego Vision Cartomizers. Plus, they don't stamp their logo on any of the accessories, which I know isn't that big of a deal, but I like it better.
