Don't buy any products!!
I bought a mod, 2 weeks later one of the pins below the tank got stuck down. After 2 months of emailing everyday, they did send me an upgrade. 3 months later the top of the mod came flying up and hit me in the face while trying to use it. I contacted warranty. Today i get an email stating that they only give out 1 replacement, and this "replacement"; which has a full warranty, is out of warranty.
