The Dome is more than adequate for me. I hear people shatter them and I only had it break once on me the first time I used it and I accidentally slammed my phone against the desk and it cracked the Dome in half. But since then I've never had it broken (except last week during shipping - lol). But that's what a screen protector is supposed to do. It's supposed to sacrifice itself before harm to your screen. It's supposed to break. I don't see much additional benefit with a Sapphire protector for the extra cost.
