New to vapes and had no idea what I was doing. I actually ended up burning the cotton to a crisp... no wonder I didn't like it. The owner was very friendly and fixed me up as good as new and gave me a little more information so I understood the correct way to do things. Needless to say I will be back. I recommend everyone checkout Dope Vapor! He also makes his own liquids. I only had time to try a few flavors and they were all so good I had a hard time deciding! Can't wait to purchase more!
