I hate the usual Gepfriemel with protectors. With my phone I have to disappear with ongoing shower always in the bath in order to bring these things. Here, the application works without any complications on the lens clean. Lens and film draw on quasi magical and Zack's attitude. You can tell not at all the recordings that a foreign body is located on the lens. Everything is crisp and clear. I'm really surprised. The protective effect is super. Exactly what I want for my GoPro. I'll use the protectors in any case continue.
