I love my 5v Prodigy V2. Cartomizers seem to be the way to go if i'm not dripping at home. I think that the only 3.7v that will satisfy me from now on will be the Juice Box. The custom made atty is said to hit like 5 or 6v on a simple 3.7v battery that lasts a really long time. 2 more weeks and I will know for sure!!!! One of these days i'll get a 6v mod. When it does happen it will probably be a GGTS. Income tax check is coming soon so I can justify spending $200+ on a mod, they just look too nice and I love any idea that eliminates a cart, ie the AFS on the GG's.
