Being a world traveler, I move all the time, changing cities, countries such as shirts. I then called my HDD died because of the regular trimballement (yet I still was carrying in a good suitable cover)
Well this time, no excuse, this HDD is a real armor! it is not yet tomb water for testing, but for everything else it is really functional, self-powered, compact, good finish, very fast delivery, small book with USB cable that can pull over side of the HDD, and even a cable extension for those who prefer a longer length (because the cable that stows on the side is really small, although practice).
Voila, product recommendable! Especially for frequent travelers! (Even need to cover the blow, although would put a double protection .. you never know.)
