Very small, light, nice and rugged look. This password nickel USB 2.0, but when I used USB 3.0, I have had only decoration. And this time, even changing the cable to another I know functional, nothing to do. Back accepted by Amazon, as always satisfied their service. For cons, I was also that of WD, but I started asking me questions about the quality of their products seems to decrease (second negative experience). For the first time in years, I will probably turn me on another brand.
