In case no rubber feet are in the process that would have been for a hard drive enclosure attached but really!
The supplied 12V power supply makes a more significant impression than most cheap power supplies that are packed somewhere to. The measured voltage of 12.3 V is fully in order and within tolerance.
Also praiseworthy: firmware update can be found at Wintech on the website has to offer also plates to greater use 2TB.
Conclusion: no scrap, but inexpensive and useful quality.
Addendum:
The first housing really seemed to have a quirk (see comment). The second has no problems, not even with static electricity.
Since my new notebook USB3 support: The Hitachi drive makes it its full speed of up to 140MB / s. Burst loudly benchmark 150MB / s and thus probably the maximum speed of this housing or USB. 3
