I only had one drive to copy so I cannot attest to many multiple uses, but the product appears to be assembled well and durable. The adapter fit well into both USB and SATA ports. There was no looseness. So as long as you are not careless, it should hold up well. I had almost 500 GB to clone, so I set up the software and let it run overnight. When I came back in the morning, it was done without any problems or complaints. I cannot corroborate the reported transfer rates, but have no reason to believe it did not perform as stated. The adapter is good enough that I would buy it again, but it is also good enough that I probably won't ever need to, if that makes sense.
