I opted for the product because I look Prime the bus with my Kindle Movies / TV series from Amazon because I always sit at the window has often dazzled by the film reflects the display as good as I now no longer at which dark scenes prima can see.
Fingerprints and smudges of course there are no more, only if times the display is please do not rub dirty, which dissolves the coating, cleaned with a damp (not wet) cloth or a cleaning cloth for displays.
Conclusion:
Cleaning: only freucht (not with a cloth / TShirt
Reflection: little
Fingerprints / streaks: no
