A couple of weeks ago I ordered 2 KFL+BCs and just coiled and wicked the first one (1.3ohm micro with cotton) and it works great! It had no machine oil odour and when I stripped it down and scrubbed it, the only noticeable sign of need was the tip.
It wasn't hard to put back together - being mindful of the air hole - but like others have said, the screws were a bit of a pain so I swapped them out with spares from my original KFL+s and although they didn't fit much better, they do have that slightly larger top so were easier to coil.
The juice channels pose no problems at all with a 50/50 e-liquid, and with the air hole screw adjusted flush with the bottom, it seems a bit airier than my originals. Because of the screws I probably won't order any more but I'm not sorry I got these (providing the second one goes the same). I can't resist the originals though. I have another scheduled to arrive tomorrow. Can't wait!
