If you're struggling to find a good glass protector for the Galaxy S7 Edge, try GPEL. It's getting a lot of attention on forums for being one of the only options that actually works, and works well.
GPEL uses reinforced glass made by Gorilla Glass. If you didn't know, is the same glass that comes installed on the Galaxy S7 Edge itself. So it should be very durable. If it ever does get a scratch, just remove it. They color-match each protector to your device for the best experience. We recommend giving this a try.
