I bought an hcigar 3.1 off ebay and it just came yesterday. Was still waiting on kanthal in the mail, so I finally built it today.
Overally very easy, well built, threads are great, can't complain..
except the vertical juice channels were borderline nonexistant.
I've heard this tends to be hit or miss in general -- I could have returned (one upside to paying more on ebay instead of FT), but I lack patience (hence paying more on ebay than FT

). I had a crappy needle file set from Walmart, and spent an hour or so widening and deepening the juice channel to an acceptable level. I actually didn't try it before this, but I'm pretty damn confident it wouldn't have wicked...it wasn't a channel so much as a gap in the threads.
Should have taken before pictures, but it was really bad. I would have drilled it, but I didn't have a sufficiently sized ss bit, and I didn't want to risk slipping and damaging (have no proper vice or press). Anyway, my first ever coil works great, and have had zero wicking issues (cotton/9 wrap 28ga microcoil ~1.5ohms) -- so far at least. I also did pick up a diamond tip dremel bit in case I needed it, but so far the file-job seems to be adequate.
Let it be known I'm not that experienced -- just wanted to give you a heads up on the hcigar I bought and the ....ty juice channels (horizontal juice channels were great btw). Also FWIW the seller called it an hcigar, but it shipped in a weird little black case (no mfr box) so I can't be positive -- may actually be a 'silver edition' tobeco or something like that. If someone knows how to tell the difference I could confirm.
Anyway, I've never wrapped a coil in my life, and was successful with a 'hcigar' kayfun 3.1 on my first go -- this leads me to believe it's pretty damn easy. Again, from what I've read, it's just largely hit or miss on the juice channels...I missed, but don't mind putting in extra effort to allow for impatience.
