The YFTK Roulette styled 22mm mtl and dl rta is made from stainless steel with a polycarbonate frosted tank and 510 drip tip. has 3.5ml juice capacity, top refill and juice control accessible by rotating the base of the drip tip. There are two roulette airflow discs included, one for mtl and the other for dl. Three airflow hole settings for mtl, 0.8mm x 1, 0.9mm x 2 and 0.9mm x 3 as well as two airflow hole settings for dl, 1.8mm x 3.0mm and 1.0mm x 4. Easy to build and wick two post single coil deck. The threads on the base are a little crunchy and could have been machined better, especially since the tank threads are PC. A spare PC tank is not included however one can bought as a separate purchase. The 510 drip tip is not to my liking, replacing it with any of my 510 drip tips leaves a gap between the top cap and the base of the drip tip. The roulette airflow discs are easy to swap out and install. Changing the airflow settings is easy and the draw is smooth.

An slightly larger updated version of the popular Swag with a new chip packed with all the features you could need, ergonomic shape, rubber coating and lightweight. It can now accommodate attys up to 25mm in diameter but some 23mm-25mm attys with a bubble tank installed may not fit due to the tall battery cap getting in the way. A full colour screen would make this mod almost perfect. If you like the size of the original Swag, Pico, AL85 and similar small single 18650 mods you'll definitely enjoy the Swag 2.

Not the best 22mm mtl rta but decent enough. The hidden top airflow is a good design but it spoils the overall looks when unscrewed and opened all the way. The under the coil honeycomb air hole design is not necessary for mtl and should have been just one single 1.2mm-1.8mm hole. Easy to build on single coil deck, deep juice holes and small chamber. Flavour is good but not outstanding.

This clone has one very important feature that the other clone and the authentic don't have, an adjustable 510 pin. Both the other clone and the authentic have a non adjustable 510 pin which will wobble and cause fluctuation in coil/mesh resistance and more than likely a short over time. Unfortunately the post clamps are not spring loaded, mesh strips and a mesh bending tool are not included. The drip tip is loose fitting so you need to either remove the o-ring in the top cap and replace it with a thicker one or find an 810 drip tip with a slightly wider diameter connection. Using a mesh strip supplied with the authentic the vape quality is on par. Wicking is much easier than on the Profile Unity rta and Profile rda. Normal single coil is possible but it doesn't produce better flavour or a denser vapor than mesh. Airflow is very open and smooth. Tank capacity is 3ml using the straight glass and 4.5ml using the bubble glass.

I already bought the SXK version and as this one was only $3 during a flash sale I bought it as a spare back up. Like the other version the flavour this rda produces is very good. The post screws and o-rings are not the best but I replaced them with better quality ones. The cap gets hot so using the aftermarket PC cap is recommended. It comes with the bf pin pre-installed.
