Just got my pro tank mini 2 and I like the vape and flavor just not a fan of the airy draw so I took the rubber things that the coils come in and put it over the bottom piece and poked some holes in it and now it has a tighter draw similar to the evod it looks a little strange but that's ok with me I wish the coils were lower ohm then 2.7 just wanting for them to gunk up so I can do a cotton micro coil
