Don't know about the temper glass screen protector though. The edges don't seem to stick well enough.
Speck cases always end up peeling or cracking but I've never owned a model iPhone without a Speck Candyshell besides for my 6+ and I doubt I'll be getting one this time. Tech21 case I love on all phones; its thin with great protection.
What company is your protector? Most tempered glass are made to fit only the screen of the phone so that a case doesn't peel it off.
