Processing is ok fit for hard drives and could be installed without any major problems. Unfortunately, the adapter no installation instructions annexed. Unfortunately, this had to serve apart from competitors h ***** x :-(. But for some savvy "screwdriver" still not a problem. All in all, worth the money.
External housing I have not tried yet, but it looks at first glance from solid, albeit in plastic (as with all products of this type, considering the reviews are to be believed). Installation of Super Drives must still be done, but I have an external Bluray burner / DVD burner, so no rush for the assembly of the external housing prevails. Copy Note for installation of slot-in drives with different heights is included. Otherwise, there are other reviews that refer to the adjustment by means of a side cutter.
