1 year from the purchase: The hard case is perfectly fit and everything works fine. Nothing falls apart and at first the whole thing also looks good. Who the exterior matter is, it can use a long time. Because - after about 4-6 months, the outer coating on the bending points and the edge begins to dissolve. As I said - no restriction in the use - but just does not look good anymore. I just now but then opted for genuine leather.
