Gorilla cases is a company that offers lots of different accessories for devices. They're all tough and well made. Keep in mind though, this isn't Gorilla Glass. It's a different company completely.
Gorilla Cases make a glass screen protector for the S7 Edge they claim is easy to install. This is a big complaint about most glass protectors. It's also 0.03mm thick and more durable than most glass options and comes as a 2-pack.
