Unfortunately, the cover has not passed the practical test: For no apparent reason, the material breaks and crumbles out. Especially the rounded edges appear to be vulnerable. I now have four (!!) small stress cracks on the sides and significant fatigue ("Out crumbling" of the plastic) at an edge. The (art) leather is not affected but the body "breaks down" slowly. And that after just 6 weeks! The device and its case was so exposed to mechanical overuse as dropping or strong shocks. Too bad. Now seems the saying "Those who buy cheap ..." yet again to come true. In addition, the locking mechanism does not work exactly - once the magnet is located on the right, sometimes not. But this is probably the lesser of two evils. My conclusion: not to be used for untauglichem corpus material.
