Kylin is airy and a good flavor tank. I only occasionally use mine because of the leaks. Have been through numerous exercises on wicking (had it for 3 months), tightening the 510, replacing o rings, disassembling the deck and cleaning the insulator under the positive clamp and nothing fixes it. I believe the leak is due to the rotary joint that controls juice flow......it does not appear to be in the air path. Again great flavor tank but I could not recommend this to anyone unless you dont mind vaping with a napkin always handy. I had the Ammit dual, same problem, exchanged it for the Kylin. I run the Kylin on the Wismec Gen 3 so with this massive mod there isnt any overhang but it (for me at least) only gets used at home. Rebuilding and wicking the Kylin is very straightforward but I do not like the leaks. If you go this route hopefully you will get one of the good ones. Good luck.
