"The AFS is intended to be used with the GGT and upcoming GGTS.
If you've been watching the GG Forum on ECF then you know what the AFS is all about. This revolutionary add-on to the GG is a self contained liquid resevoir and atomizer (replaceable). It automatically feeds the perfect amount of e-Liquid to the specially modified RN4075 atomizer inside. This is an advanced user item and we do not suggest new users purchase the AFS."
I wish I had some money to burn I would like to play with the Automatic feed system.
