First of all, yes it degrades the quality of the Retina Display, BUT nevertheless I forgive 3 stars because the advantages are obvious, you can read much better in sunlight than reflective films and for me the best advantage fingerprints again, never again people via mobile phone the wipe is madness. applying the film without bubbles no problem a bit, it took had the film briefly entfusseln (preferably with glue rollers) but wars after no longer a problem. the film feels super to the fingers glide much better than with a smooth film and better than no film. man can access calm if you can live with that, the display KINDA deteriorated. To each his own
