Scratched your screen!

At first glance, this shell appears to be well thought useful. Functioning it does as indicated in the description, even if the magnet could be a little stronger, holding the tablet in an upright position. The inside of the casing removed even dirt and fingerprints from the screen.
BUT: The small piece of metal that is held in the closed position by the magnet is located directly on the screen glass and causes even the smallest back-and-forth movements (in transport in bags) irreparable scratches present thereon.
In my view, the meaning is lost in a protective cover when the device also damaged!
