Thought I had responded to this before, but one thing to be very careful of, when it comes to the curved glass tempered glass protectors. Most of the reviews, for the S7 Edge curved tempered glass protectors, indicated that they did not stay on that well and the glass would lift at the edges, which would allow dust paticles to get in and be trapped under the tempered glass.
I have one on my Blackberry Priv and it seemed to be much better than the reviews for the S7 Edge (and Note Edge) curved tempered glass protectors, until I noticed that there was a dust particle that got in on the bottom, as well as the center, of the glass protector. I didn't really care, since the device still worked fine and overall the screen was protected.
Just something to keep in mind, prior to jumping in on a tempered glass protector that accomodates curved edge design.
