I own the Smith mod. I bought it because I like the fact that it's warrantied by Beyond Vape, and not by Asmodus. I like the fact that there is no unusable touch sensor on it, instead it's got kind of a wide groove across the top. It took the ipv upgrade perfectly and performs really well. It also doesn't have that starry field panel on it. It costs just about the same as a regular ipv, I guess. For me, it was a good buy, I don't use half of its potential but I can fire sub-ohm, which was my primary reason for buying it.
