I'm new to Vaping and a friend took me to the Roxy Vape shop. The staff was very helpful and patient with my questions. They set me up with an istick TC40w and a tank. Trey gave me proper instructions on how to setup the new unit and the new tank. I got a free silicone case and a silicone tank ring. Dave, Joe, and Trey are very knowledgeable & they carry an extensive line e-liquid/e-juice's lines. Check them out, you wont be disappointed.
