I purchased this to clone my existing HDD boot drive to an SSD I purchased. It arrived attractively packaged, with a very innovative cord support that ensured that there would be no snarls or other damage while in transit. The adapter is well constructed and fit my SSD perfectly. After I finished, I used the card support to store my adapter for future use. I have to say whomever designed that card support card was a genius. It basically is a piece of stiff cardboard with a layer of foam rubber the thickness of the connector end, with a cutout for that end to fit snugly into, and a spiral track cut out of the foam rubber for the cord to fit into. It is protected and guaranteed not to snarl.
