One can argue surely, must be whether "Ultra Clear" (women say any more "Yes", since it has a Behelfssspiegel go when the Kindle is off). Since we here rather "Black on White" who would possibly rather "Matt" recommended. What then leaves a slight "diffuse" font-impression. But - everyone must test for themselves once; I have both versions it (yepp - 2 Kindle in the family), and both are recommended when it comes to the protection of the display.
Combined Impression: A good, useful and effective addition to the Kindle, recommended for anyone who uses it regularly and would like to maintain its value.
