So to be clear is the Made-in-Germany and it shows from the opening: it is heavier than plastic and it gives a (good) solid feel. Installation is easy (20 minutes) on my Macbook Pro 13 Late 2011, thanks to the tools provided and the doc (GACE but also a tutorial that you find on Macg.co). Coupled with a 830 SSD from Samsung in Fusion Drive, my mac is reborn !! Ok a little more expensive but in the end we always get what you pay.
