First there are the set screws, which are used for hard disk fixation in the housing. These are pre-threaded and thus more or less connected to the housing in the delivery. The problem that occurs, however, is that by the transportation and thus resulting vibrations loosen the screws. Due to their construction, I had one of the two screws are looking for "IM" housing and having a lot of patience herauspulen them with the included screwdriver to replace.
Then there as the next point, the fit of the three holes for the mounting of the adapter housing in the MacBook itself. Here you have firstonce all three screws fix "loose" and then tighten gradually. You screw a first screw firmly to the holes in the MacBook in the other two screws can no longer meet and you zerwürgt may take longer screws on the plate of the adapter housing.
As a last point of criticism I would like to mention the plastic clip which is to prevent the hard drive it to slip out of the SATA connectors. Although this sits well anchored in the adapter behind the hard drive in it, but is very loose. The heist, he wobbles. And shake that is so strong that if you. His MacBook from one room to the next Carries, you can hear it rattling in the MacBook ... that's an absolute no-go
Otherwise, it does what should Tuen it and sees in black and very chic (as long as it is still visible on the desk).
The external SuperDrive enclosure makes a quality impression (albeit made of plastic, but you do not see him), but there are also here a criticism. The built cable bends, due to the construction shape upon exiting the housing to the side and is thus not just clean out of the housing. This could certainly be eliminated by a proper strain relief.
The supplied screwdriver is magnetic and do their job without complaint. Only the Elektrospartel (or whatever you want to call it too) has quickly given up the ghost at play around and has been broken.
One star deduction there because of the shortcomings mentioned that I've found and a second star deduction there because of the really high price and the still emerging defects. But the price is probably because it is this is a supplementary product for Apple devices and it's customary for the market to hit here one or two dollars more on the manufacturing and development costs :)
Conclusion: Does what it should with some flab on the stomach and is it very expensive.
