I dropped it onto carpet, laminate, vct tile and linoleum, I think I threw it a bit over my head a few times which would make it about 6, 6 1/2 feet. I had the screen guard on but I hated the gap, as it's not a full edge to edge. I did lightly hit it with a hammer while it was on and my phone was fine. I ended up taking it off after I dropped the phone not realizing there was gravel/rocks all over the floor, and the screen protector ended up looking like a golf ball with all the dimples it left. But agin, the phone was fine. I can't recommend the rhino shield enough, although I personally prefer a benks or similar edge to edge screen protector for aesthetic reasons.
Edit: forgot to add it feels very grippy, but smooth. Definitely adds sufficient grub without feeling rubbery
