I won one in a HeavenGifts contest not too long ago. I REALLY LIKE this thing. Mine does have the top AFC, but I tend to keep it closed. I'm not crazy about the wide-bore tip (and I haven't found any adapters yet), but it still sees use about once a week or so.
For building, LOVE the velocity-style deck. Wicking, I'm using Shiseido cotton. Make sure not to over-stuff the juice channels. I just barely get the tails in the channels. There is a ceramic block, if you only want to build one coil. I'm running dual claptons, about 0.5Ω. I don't crank it terribly high (don't like super-warm vapes in general) I'm pretty much a "middle-of-the-road" vaper - not too tight of a draw, but I'm not going to fill a room with klowdz.
I do get a teensy bit of "oozing" around the bottom AFC, and the only time it really leaked on me was my first build, when I didn't have the juice channel thing figured out yet. Since then, it's been rewicked maybe a half dozen times. Have yet to put another build in it.
I'm not displeased in the least.
{get one........ dooooooooo eeeeeeeeet}
