I got the original one super cheap when ecig.com first stocked them. Compared to my ipv3, 4, and Li, it does TC much better. Until I got my DNA 200's it was all I used for TC once I got it. The G2 is definitely the one to get now, as has been said, upgradable and not just Nickel for TC. And the Slice does look awesome. DNA 200's still win for TC, but I'm comparing to the original one. It's a well made device, now that the pricing has become more appropriate. I never would have gotten one if not for the deal. I'm glad I did.
