The roller is a great mod. I found it was the kick giving me the problem. Its my most expensive mech as well. The threads and the button are perfect. I can't decide what to get next... the Chi You mod, the Gus telescopic mod or the 69 mod. Got my Roller from Vape Revolution. They cary everything but don't have a website yet so you gotta call them to order. They're in California and are really nice and knowledgeable. I was having issues deciding what to get, the Roller or the 69 and answered every question I asked them to help me make up my mind. I'm glad I found them because everything that's really good is coming from overseas and I don't really feel like ordering out of the country ya know. I'm in Florida and it only took like 3 days to get here.[Report].[Edit]
