I couldn’t be happier with my sapphire glass. I upgraded to a refurb SSS4 after the S5 was released. I spent the last 5 days hiking more than 60 miles over rocky AZ trails, climbing over boulders, and bumping into almost anything imaginable. I have a couple of predictable dings in the case, but the crystal is flawless. My aluminum 3 would have numerous scratches on it, I’m convinced.
