There is an error on their website.. i wanted to order the replacement glass for the TFV 16 lite smok tank and if u go to the tank it has a reorder of the glass right under it but it’s not the correct glass. They have the TFV 16 smok glass which is for that tank and it won’t fit on the lite tank Anyway, i called customer service the next day when I realized it’s the wrong glass and i spoke to a woman Gayle or Gail and she was so helpful and kind. She took the time to look up what i said and she agreed with me and said when u get it ship it back we will send u a return label by email and u will be refunded for the entire order. I. Definitely recommend Direct Vapor. Their customer service is excellent and that is very important at least to me
