Query: China junk

I bought this item to transfer data from my old laptop drive to my new one. I was able to get all the data needed, but two days later while backing up data the thing died on me never to run again. I plan to attach the SATA adapter to a different power supply to continue using it, but for anyone who doesn't have electrical skill to do the same I say: DO NOT BUY THIS PRODUCT! It is very cheap.
