Tech Armor Ballistic Glass
Tech Armor has been one of my favorites in recent years with their Ballistic Glass screen protectors, which are now available for the Galaxy S7.
It's a durable, strengthened, and extra reinforced durable glass, but they don't stop there. It has the same anti-scratch and nano-coating to prevent fingerprints as actual screens on our phones, rather than just a tough piece of glass to cover your phone with. Meaning it's the best of both worlds, crystal clear, and very durable.
Tech Armor Glass Galaxy S7 screen protectors also don't cover the glass 100%. This is to prevent pealing where it will eventually come off or get dust underneath, and it allows owners to still use a case. Something we can't say about some of the others. It's the perfect middle ground, available now, and low priced.
