When I opened the package, I had a surprise when i saw it was not what they said to be! It is actually a 1.8" ZIF to 8+18 MINI PCIe converter, not a 1.8" ZIF to 7+15 SATA!
So now i have to look for a new converter from MINI PCIe to SATA, great!
UPDATE 14 Aug 2013
After I posted the review, I have been contacted by the customer service regarding my problem, telling me that they will try to help me. After a few days they've told me that I will get full refund and that they will update the description of the product. Until now, the customer services are great, helped me every time I had a problem or a question, so I'll come back with an edit when I'll receive the refund.
UPDATE 20 Aug 2013
Today I received my full refund for this item.
Thank you MiniInTheBox and the great support team! I will look forward to buy again from here!
