There are sellers who sell duplicate and non authentic products under the name of reputed companies. I had brought the matter to notice of the site customer support as I was sold a Transcend Ram 4BG, which was made by another company and not any companies listed by transcend, the packing was also seemingly real.
Even after making the complaint, they did not do anything about it. They were not able to send me an original product, rather they cancelled my deal.
