soooo glad to find this forum, ive been reading for hours! vaping is new to me, I am like a dog with a new bone, I LOVE IT!! I had done a lot of research (so I thought) and bought Smoketip starter kit two weeks ago. Reordered 30 more cartos that should have been here on Saturday, no luck. I began frantically looking online for somewhere local, and began reading about juices and other kinds of models. Really getting excited! Did have to buy some smokes cause my order didnt come in, grrrr...I was going to buy another starter kit from them so that I would have 2 more batteries and another charger. Kit was only $59. Im glad I didnt do that yet! Im confused about batteries and units, but I have time to keep reading. HOPEFULLY cartos come tommorrow, should last a little while. I want to try juice in the used cartos, from what Ive read, it seems I can do this, yes? Does anyone do that regularly? I am already not happy with the battery life and will have to figure something else out later. but for now can I just buy juice and vape at will???!!! Thanx, Laura
