Review on Enhance Desktop Connectivity with J-Tech Digital PCI Express SuperSpeed USB 3.0 2-Port Expansion Card by Brion Pine

Very cheap assembly, never had much speed and basically died after about a month. It no longer shows up when using USB 3.0 and ONLY works when using USB 2.0! Transferring back and forth took forever. The cover was loose from the start and the logic board inside was never aligned with the card slots. When I inserted my 16G MicroSD card, the card actually slid OVER the PCB slot and INTO the case, forcing me to remove the (already loose) cover to get the card out! They do offer to replace it, but the cost of returning it would have been the same or more than the original purchase and not worth it. It's in the trash! No, they didn't even send a shipping label. It will be ALL MY COST to return it to you. And they only supply a VERY SHORT USB cable for the device. I'm LOOOOOONG good at computers and electronics and this was VERY disappointing. NOT a good product. NOT good customer service. NOT a good experience. NEVER AGAIN and DO NOT RECOMMEND using this company.
