I've had this cover for a couple of weeks and the corners have come away from the outer case, plastic has cracked on one of the inner corners.

I love this case, as a user of S View of Samsung Galaxy S4. This is much improved in term of usability. The application support is wider and the overall experience improved. Unfortunately, this is still not at the same level as the implementation on Note 4, which is far more customization, including clock faces! What I enjoy the most is the ability to hold the device with one hand as an open book, cool! I use the gold colour one on my gold-platinum Galaxy S4, matched with my gold keyboard: perfect!

The corners started cracking and chipping after 1 week. Completely useless case (in terms of protection) as the phone just falls out of the case. Have not dropped it once.
