Welcome mpakluck to ECF! I did go to the Jasper & Jasper website and I'm not sure what kind of connection they use, looks like maybe a 306. If you are going to buy a kit Blu is ok but way overpriced. Go with a basic 510 kit and buy Boge Cartos and fill them with an e-liquid, you will save allot of money this way! If you like the size of the small batteries that is ok, but if you spend enough time you will soon find the GREAT pleasure in Variable Voltage
vaping! Devices like the Provari, Lava Tube, VMax, Vector Variable Volt to name a few!
Check out VaporBeasts 501 kit, two batteries, 5 pre filled cartos...$32.00 bucks with free shipping. The kit is as good as my the overpriced brand named devices. If you have a chance explor the Bolt at VaporBeast, they are big but battery life will get you through an entire day; and their juices are great!! PM me if I can help in any other way, it all can be a bit overwhelming at first, but it can be lots of fun too!
