Have ordered the items, in order to simultaneously operate in my 15 "MacBook Pro (early 2011), a SSD and a HDD. I read me first smart and noted that the HDD is always so belongs a part of the product in the Carrier, because it leads to crash otherwise. After the instructions came by email (even before the article eintrudelte), I saw that there should be a well-solvable task. This unfortunately confirmed not. In my MacBook SuperDrive is fastened with Torx screws, which made it difficult to expand. Following the expansion, I put the device in the external housing. However, this is made of plastic and not like the picture visible from high-quality metal (also is not in the description). The closing of the case also was only with great effort. The drive is also located not very good in the housing and can not be fixed. Ejecting disks is not possible, because it is hindered by the housing (remedy the spreading apart of the slot).
For installation of the carrier: The installation turned out to be even for an experienced PC screwdriver as a real challenge, because the holder was not working so that they could fasten the screws on the holder.
Conclusion: It can be observed large quality defects and was not worth it for 60. However, it does the job for the most part.
