I appreciate the feedback. Ended up returning the defender back to otterbox. It is just too much case for me. Have a tough armor coming in for both the wife and me. She will have the white and I will have the silver. Might get a few extra back plates for extras.So you went with the Spigen? That's a good choice. There are other glass screen protectors that are even thinner such as the Mime feather glass + (.15mm), or iloome screenmate flexible glass (.12mm). Just some more suggestions incase anything happens to yours and need a replacement.
Though I don't see why you'd really need a screen protector if the case has a lip so when you set it down face down the screen doesn't touch the surface.
