I shopped at Best Vapes and was very disappointed. I went once to buy a tank. The person that was there suggested that I buy a specific tank, so I bought the one he suggested. When I got home and tried to put my ecig together with the new tank it wouldn't work. So I went back to the store and the store manager was there working. I explained that the tank wasn't working. He didn't offer any help and told me there was nothing he could do about it. I was pretty angry that he wouldn't try to help me. I do not recommend this shop, and I give them a very low rating. I will not ever return to them.
