I've tried a few of these copiers. This is the first that worked as advertised. It's plastic, of course, but looks very solid and well-made. I highly recommend this product. I duplicated a 1TB drive but I can't tell how long it took. I started and went to bed, and in the morning everything was ready. I checked the files (all movie files for my DVR). I randomly tested some of them (couldn't play all 300+ movies :)) and they all played as expected.
