I purchased this product about 1 1/2 years ago and since then in use. I have this hard drive then bought by data exchange on with friends, which is why I have this hard drive often also awarded. To this day, there were no defects, everywhere she has always worked completely. With the plug I have no problems, even if the hard drive was not always treated well by me. The housing is made of plastic and scratched so easily, what personally but just in a hard drive at all me disturbs me. The transfer speeds are very good, actually the same as in my internal. Conclusion: For the price a good external 1TB hard drive.
