Belkin screenGuard F8W355vf Glass Screen Protection for iPhone 5 / 5S / 5C INVISI GLASS, 0.2mm ultrathin, high scratch resistance, clarity, absorbs shock (Wireless Phone Accessory)
Very good product, effectively invisible. But as always the point that needs particular care regarding installation. I isolated myself in my bathroom but dust and managed to get between the film and the screen. Next time I will use extra hairdryer.
