I grabbed one from the Facebook group buy with Carolyn and it's hit and miss in certain areas.
First, it came very rough. The glass is rough and the wick holes were rough. I redrilled the wick holes and they turned out fine. I don't really know what to do for the glass so I won't mess with it. I drilled out the top air hole to 1/16" and it was ok, but I also drilled another hole over where the second wick is. Huge difference. I ended up drilling that other hole out to 1/8" and it now has a very airy draw (which I like). I am not really a cloud chaser, but it's quite amazing how much vapor this thing kicks out. lol so much, in fact, that I am refilling the tank about every 4 hours. Using ss cable with mesh on the wick above the deck, it is just soaking up the juice.
I have used quite a few genny style tanks and I have never had one hit like this in dual wick configuration. I get more vapor and better taste than most of the RDA's I have used in dual coil configuration. It does get insanely hot though. Another problem is the drip tip hole. At least half of my drip tips wont fit in the hole. It's not just an O-ring problem, but the stems won't fit. I could drill that out as well, but i'm not gonna bother. My only other complaint, and it has nothing to do with the clone because the original is the same way, is that the wick holes are too close to the negative screws. It's almost impossible to keep your coils off of the negative screws and this can cause hot legs on the bottom.
My girlfriend ordered one on Congrevape, but we have no idea when it's going to ship so I don't know who made it or how it's going to turn out. All-in-all, I am very happy with this thing. Great buy for the price.
