Purchased to protect the screen of my MBPr (compressed and transported several hours a day in a backpack overfilled) against the mark of the keys that had finished my MBA last unprotected and subject to the same use, become permanent. The loss of brightness is almost nonexistent; the screen is matte, which can provide comfort and quality Retina Display is almost 100% preserved. My fifth purchase iPhone / Mac in this range, Moshi iVisor despite a low price; always satisfied.
