I don't think that's the VB one.. I get one with my vamo and it's really cheap... The tank is marked like a Vision only to 2.8ml but the heads and the heads are a little different than the one aClear. It looks like the metal above the coil is longer.. I rebuild evods all the time, but this looks like a pain because the coil sits so much deeper than either the evod or even aClear.. or at least in the picture it doesn't look as deep as what I have in my hand..
I just wanted to check it out for $6 bucks but I don't think it is worth my time trying to rebuild it.. On the plus side it did work pretty well and I was able to vape the thing almost completely dry..
The fasttech one for $5 shipped looks like the aClear...
I'm not knocking the Vivi...it works. I was looking for a metal tube for it when I stumbled on the aClear. I think I'll get an adaptor and a ProTank instead lol.
