Separates himself permanently from the computer, so that open files can go wrong!

I ordered this external HDD enclosure to connect an SSD with my photo library on the computer, because I thought it will be faster than my old external USB2 hard drive enclosure, which I previously had in use. That was, in fact, Aperture has opened the library faster, and editing photos very fast.

"SSD before disconnecting or powering Eject" - the SSD was separated, and I was right in the middle in the Order of photos: After single pair using days suddenly appeared a message!
But the cable stuck still in there, only the SSD was no longer visible in the Finder!
Cable out, cable in, "library is damaged. Repair?"! So 'a shame!
Okay, I thought, was probably your own fault and have the cable touches or so, and the SSD was separated, although the cable was still there.
The next day the same again! And again!
With the old hard drive enclosure and with the many external hard drives that I have, is what never happened to me!
Well, then we went back, single pair days it worked perfectly.
And today it started again: I have the SSD connected to import new photos. After about 3 hours, the SSD has independently separated, and I have the laptop does not touch at this moment! The library was damaged by naturally. And the repair process, the SSD has separated again, and again!

It can not go if the thing can not operate safely, it gets a star and from back to Amazon, fortunately not to the 30 days after the purchase!

I do not know if that is on the drive casing itself or on loose contact in the cable, the cable's "unique" with two USB3 A plug so I could not replace it.
