PROS
- Excellent machining - Shiny polished finish with no blemishes - Clean of debris and machine oil - Bottom airflow design - Seamless top cap [no drilled air holes] - Difficult to flood / over-squonk - Easy deck to build on - Nice included drip tips
CONS
- Airflow feels looser than I think ought to be - Only one spare deck screw included - Bottom laser etching could be better
First impressions out of the box are positive. The RDA is nicely machined and buffed up to a mirror shine. It's one of the best exterior finishes I've seen from YFTK. I didn't notice any swarf or machine oil and all the threading is excellent. Included with the RDA is a threaded black POM top piece, a spare deck screw and o-ring, and two drip tips - one made from stainless steel and the other black POM. The stainless steel drip tip is polished up to the same mirror finish as the top cap and looks outstanding. Both drip tips have dual o-rings for a secure fit. Lastly there's a 18mm - 22mm stainless steel beauty ring, although I never use them so I can't comment on it.

Building on the Karma is easy. The deck screws have big flat heads which make it simple to trap the coil legs. Because the Karma has bottom airflow you must ensure that your coil is placed properly over the air hole. This necessitates coils with longer legs than I'd normally use but it has no apparent effect on the function of the coil. There have been no hot spots on the legs when using stainless steel resistance wire. The juice well is deep which makes wicking easy since there's lots of room to stuff your rayon / cotton. While the 510 juice hole appears smaller than most, the deck is quickly juiced up with a squeeze of the bottle. The juice port sits almost flush with the bottom of the well so most excess juice will be sucked back into the bottle - I'd prefer it to sit around 1mm off the well floor. The air hole is a good distance above the juice well and I've yet to have a flood.

The air hole is pretty damn big as far as 18mm MTL RDA's go. It's definitely larger than the Speed Revolution, and I think larger than the Strike 18's widest setting. I would compare it to the Shift RDA when fully closed as the draw resistance is almost identical between the two. It's still very much a MTL oriented RDA but it's about as airy as I'd be willing to go. That being said, even though it's more airy than I'd usually prefer I'm really enjoying the vape and have no desire to shelf the Karma anytime soon. If you liked the Shift RDA you'll almost certainly like this. It's not the quietest RDA, but the sound isn't loud enough to be noteworthy. There's no whistling and the inhalation sound doesn't stand out to me as unusually loud.

Since the air hole is directly under the coil the vapor is never too hot. The coil gets a perfect shot of air directly on middle of the coil. The Karma produces a ton of vapor for it's size, more than other 18mm RDAs, and I assume this has a lot to due with the positioning and diameter of the air hole. Another benefit of the bottom airflow is the fact the top cap doesn't need to be lined up with the coil. Air is drawn in from the side of the base so there is no need for proper orientation of air holes in top cap. Having a solid top cap looks sharp and is surprisingly convenient. It's something I've quickly grown to appreciate.

On the Moldy MTL scale the YFTK Karma comes in at a solid 8.25/10. I've deducted some points because I think the airflow should have been reduced more. I've heard rumblings on the forum that YFTK didn't follow an exact copy the original Karma's airflow dimensions; apparently the YFTK air hole is wider than the authentic and not tapered in shape [but I can't actually confirm this at the time of writing this review].

I'd recommend this to anyone, but I would first look at other manufacturers to see if their airflow design more closely follows the specs of the authentic Karma.

Well-made Flavourful Leak resistant
CONS
only BF pin included 1 airflow setting
I've been looking for a 18mm or smaller bottom airflow MTL RDA for a while. This fits the criteria I've been looking for. building it is surprisingly easy, Even though it has only one airflow setting and I'm used to a looser MTL airflow, this is a great flavourful RDA with no spitback.
