Im looking to buy a mod pv today as my joye 510 isnt really cutting it for me, the battery life just isnt practical for me being that im home all day. Ive been having problems with thicker liquids with it also. I would like a pv that can do 3.7 as well as 5v or 6v(so im not limited to only a high voltage pv), have a battery that will last the entire day(or longer) and will give me better vapor and taste. The chuck looks like a good choice, but i would really like to order everything (batteries, charger, attys, etc) from one place. Any opinions would be greatly appreciated. Thanks
