The case fits perfectly and completely, and is easy to install. To this effect fortunately virtually not on (that was for me personally also very important). It has quite good grip, making it much better in the hand than the Macbook per se.
For the price it is really unbeatable!
Even the delivery was very fast. With Prime, it was right on the next day at my house.
Regarding longevity, I can now, of course, give any information ...
