I recently purchased a Kanger Protank 3, and I had a lot of problems with it. Flooding, juice getting into my mouth etc: All the New user syndromes. Little did I know it was the way *I* was using it that was causing the problems. I went to my local shop (Vaporwize in Memphis), and Andy took the time to explain to my how to Vape correctly. I was sucking on it like a straw, not gently. After I changed the way I hit it, the entire experience changed for the better. Well...little did I know there was an actual learning curve in vaping correctly, and thank you Andy for taking the time to teach me!!!
