Nice review by Scott, he's pretty much spot on on everything. Pbusardo just reviewed it as well with similar talking points. Might as well post it below in case any are browsing this topic considering picking one up.
Many seem to be complaining about the build quality, but honestly i really don't feel like it's that bad. It's certainly not "good" but it is what it is, a pretty cheap (in quality and in price) VV box mod that houses impressive power for its size. I love the 18650 battery event tho it's so small.
My one complaint thus far, would probably be with the 510 connection. There is no drip well, and it's not recessed so ego style cartos (Mega carto, vision clearos) won't work. I bought a 510-ego adapter, but the dang thing got stuck on my vision clearo prompting me to use needle-nose plyers to screw it off. Once unscrewed, i noticed the thread casing that goes around the connection was warped, more oval than circular. I tried bending it back to shape but it didn't work. Pitched it. I'm perfectly happy just using cartos and carto tanks on it and defaulting to my ego-c twist for the visions, but it would be nice if it had an ego style connection, especially with how popular the visions are right now.
