Stylish and fit, but more important than design function

The cover fits perfectly and looks great. All ports, buttons and speakers are free. The design emphasizes the thinness of the device, there is no magnetic closures or snapper, which would apply in addition.
The stability in the Typing position is limited, the device from slipping on smooth surfaces on the lower edge of getting away, because the built-in rubber feet only in the viewing position have contact with the pad.
Overall, the product is useful for me with a few flaws. But hopefully it will last longer than the 3-month manufacturer's warranty suggests (wearing part?).
