for me this is not a mtl tank. the reason i say this is, i cannot mtl with it! over all it only leaks if you keep it tilted or layed on its side. only then very little from the air adjustment holes. when i set the air hole to the smallest setting i get gurgling really bad. open up the air and a few hits its gone. the draw is flooding it but dunno why, so more then likely its a me problem versus a we problem. i use this with a 3.0mm 26awg kanthal single coil ohms out at 1.2.
use it on a voopoo at 18w. it is easy to wick and a pleasure to use. kinda weird but i get more flavor from my kayfun 5 then this. but the hit is better on the siren 2 with the air wide open. almost the same draw as the kayfun. no weird whistling no leaking no flooding when filling.
would i buy this again? bet on it
