SXK Hussar RDTA: Hands on First Impressions http://www.3fvape.com/rebuildable-a...silver-316-stainless-steel-22mm-diameter.html Converted the Hussar RDTA to BF as soon as I got it. (Link above is to the version with BF pin included.) Only been vaping for a half hour (kanthal 24g 3mm 5 wrap @ .5 ohm) and I love it. Warm vape, fantastic flavor. I can tell already that among the dozen or so bottom feed RDTAs I have, this one is definitely in the top tier for modest builds. Excellent SXK machining, fit and finish. So small, no telling it's an RDTA from the outside. Especially small, low chamber for great flavor. Smooth AFC operation. I have it half open for slightly restricted DTL. Easy to build, cutouts for coil mandrel, small post screws. Not much room to trap thick complex coils. Bears repeating: FLAVOR!!!
