Anyone have one of the Got Vapes Ultimo Vision 3 and how is it? It seems pretty small, which would be good for stealth vaping. Can't figure out if it will take a regular 510 carto, tank, etc. It comes with 2 vision extremes 360 cartos and said it only takes those or one with similar or smaller width, but doesn't say what that width is. Any help and opinions are appreciated.
