even thought i know i'm just lucky LOL. So I bought this cheap 25 knock of electric auto cig before i bought my 510. says on the side of the battery G-4 FDA registered #3007697818 It came with 5 prefilled carts when i got it and a usb charger. Well we ran outta the carts a while ago.. and since I got my juice.. i ripped the cheap polifilter out, stuffed in a small tea bag and then dripped 2 drops on the atty and now it's vaping like it never has before! Pretty proud of my self for the most part lol. Even if i ruin it.. it was cheap and i have no idea where to even grab replacement attys for the thing. The smoke shop we got it from only sells juice and carts for it lol.
