I'm trying to buy an Xmas present for the wife who wants to quit smoking. I've done a lot of reading to get myself educated and STILL have questions..!! But can narrow this down to these - can I use the Geekvape Aegis Mini as an MTL using salt based e-liquids? I'm hoping there's a high resistance coil I can use with the Mini set at 20W or less. Tank recommendations? Thanks!!!
