HCigar 3.1 Kayfun "Clone":
First off it comes in a really nice travel case
The machining is excellent, threads are silky smooth, joints almost dissapear. Definately has more weight to it than a Fastech KFC. I really like the Matte finish but it doesnt quite match the brushed SS finish of the SVD.

I installed the SS tank, it does come with a plastic tank, translucent, not clear as with the R91C. It does come NOT cleaned, has a definate machine oil residue on it... you need to clean it 2 times to remove the oil... and yes the oil does taste nasty ( I cleaned it once and rinsed 3 times... obviously needed 2 washings)
Airflow control is very nice, can be shut down to nearly nothing and opened up to being quite airy...
I put 100VG 36 nic Legend in it ( forgot to cut it with glycerin) and WOW ... the nic hit was intence ( too much really) the flavor is rich, almost moist. Vapor temp is mild almost cool ( 10.5W with 1.7ohm 30ga 5 wrap on a 1/10" bit cotton wick). Tried to make it dry burn, couldnt do it. The juice kept up with the demand. Dropped the watts down to 8 and still produces plenty of vapor, taste seemed to drop out a tad tho.
If you are thinking about a 3.1.... the HCigar version is the way to go... and it less than 50$...
