This IS a big problem in my opinion. Most of the products used in
vaping are manufactured in China. There are no standards or regulations for most products made there. It is a very cut
throat business where smaller, lesser known companies make look-a-likes of popular name brands, (such as Joye, Vision, Boge, Smoktech, L Rider, etc.), which are often of a poorer quality or with less quality control of parts/manufacturing. This seems to be common and almost expected business practice to them. Having said that, it appears that many American vapors are out to find a bargain, find these products for cheap believing that they are getting a great deal. Well, if half of the purchased product is DOA, is it really such a great deal?
I have to believe that many of the vendors are helpless as the middleman. They are buying products in large quantity. They have to be taking a bad hit if customers demand a refund. Interesting that cartomizers are frequently exempt from any guarantee...probably because their defect rate is so high.
