this stuff isn't new...it's been done alot the first one that comes to mind is the Kraken,,,,it's not a genny that any genhead really cared for..it was one of th first dual coil gennys with a an adjustable airflow which for the time it was released the air flow was much bigget than any genny,,,it wasn't designed for genny users in mind it was designed for cloud chasers and most people stuffed cotton in them....more recntly the origenny was released with a big airflow and two 4mm wick holes for cotton builds.. and twats have been stuffing cotton in good gennys for a long time,,,,,but for whatever reason it is not something that really ever caught on...the sub=ohm tanks came along and let drippers blow big clouds with out dripping.....but these drippers with what used to be called self feeding tanks seem to me to be a better solution than sub ohm tanks I like having the coil closer to my moth thank the sub ohm tanks......I think the main diffrence with this current round of attempts is that they have a massive airflow on them.
