The Screen Protector is scratch and smudge resistant. As Far as screen protectors go It does its job and protects the screen I do not notice my toddlers dirty finger marks as much. There is no noticeable delay in responsiveness either. I do how ever wish it was a little more Anti Glare But over all I like it and its kept my screen from getting scratched.
Drop Protection on the Aegis is great its got double thick silicone on all four corners and has a great shock absorbing design. My Toddler has dropped it several times since I received this case and It still works great. The Polycarbonate outer shell does a great job of protecting hard impact.
Anti Skid Design Well it works there is just enough of the silicone peaking out from the hard polycarbonate shell to keep it from slipping out of your hand or accost the table. (Ask my four year old who tried it play air hockey with it the other day.)
