Phone arrived at the local airport a couple hours ago, should be at my door tomorrow as expected. I've got a Spigen Ultra Hybrid and an ESR full-coverage screen protector ready and waiting for it.
I actually went without a screen protector for a couple of years on my 6s Plus and never got a scratch, but eventually I got a little tired of being on edge and put a tempered glass protector back on. Good thing, too...not long afterwards, an incident occurred that put a huge gouge down the middle of the display. When I saw it, it was like that feeling you get when you drop and break something expensive. Fortunately, all I have to do is peel off the scratched protector and voila, good as new.
I've got tomorrow off from work, so this is gonna be a good time.
