First level quality manufacturing, I received a model with a piece that walk inside. -1 Star.
Then the fan noise is just horrible. I like being next to a hair dryer. -2 Star.
And now, as told by someone else, the connection is not absolutely stable. As soon as you copy files from the PC to the hard drive, the USB connection is lost. - 4 stars.
So unless you have only clone drives without using the PC, I advise you to go your way.
