Got mine in Tuesday from FT. Pulled the stock coil immediately and gave it a bath. Did a 7 or 8 wrap 26ga 3mm spaced SS coil came out to around .65ohm. Wicking took a few tries to get the juice holes properly filled (trimming a bit long 1mm or so past the channels and tucked in worked for me).
After a few days on this tank, I won't be going back to my previous ADV Hurricane tank. Got dry hits on the Hurricane unless I dialed back the wattage, on this one I'm running a conservative 22w and loving it. Not huge clouds, because I don't care about huge clouds. It's very satisfying and no dry hits, NO LEAKS, and super easy top fill.
This puts the KF4 top fill/juice control to shame (sorry, I had many of them when they were THE THING). Deck access without draining the tank is easier than any I've had access to so far.
All around, a solid tank. For 20-30 dollars depending on exchange rate (canadian here) it's hands down better than the KF4 which cost MUCH more than this, heck even a clone cost more than this when I got my first one... Anyone that's a single coil fan ala KF decks won't be disappointed. Don't hesitate, GET IT if you're even slightly interested, you won't be sorry.
The bottom "post hole" cavity thing will be a bit to get used to if you're used to wrapping around a screw like me, or using regular post hole "velocity" decks. It's not bad at all once you get used to trimming the legs to the right length.
Sitting on a JayBo Reuleaux DNA200 with the black orings, it's really as good as it's gotten for me so far with my style of vaping.
Cheers
