John sold me my Kangertech unit & 3 bottles of juice which I love. When my tank started leaking, he suggested a fix that worked perfectly fine. See John for any questions or concerns. He is a true "vaper" Updated the review because compared to the other shops I've been to. They need to offer more house juices and should especially support all of the Maryland local e-juice companies! No High Seas Liquid or Mad Scientist Ejuice in stock.
