I have been buying everythiung from V4L and I am very happy. I am buying juice now for the flavors that I enjoy the most and refilling the cartos myself. I am wondering if the batteries are usable with any other brand cartomizers? I am vaping at 36mg as I am a pack and a half a day smoker and have not completely quit yet. My cut off day is my birthday Dec 28th. I was giving myself a 4 month transition time to get used to vaping and so far I love it. Im addicted. LOL.. can anyone tell me where else I CAN ORDER THINGS THAT ARE INTERCHANGEABLE WITH V4L batteries and chargers etc... Any help would be appreciated.
