I also use Otterbox and swear by them. Have had them on every phone and only broke a screen when I slipped on ice with the phone in my hand and landed on it full force, screen down on gravel (no way any case would save it in that situation). My dad has his 5s fly off the roof of his car on the highway on-ramp. Other that some melt marks on the case from the skidding, the phone was fine. Had one incident awhile back when I bombed down a hill on my longboard, got speed wobbles, fell off, and landed on left side where my phone was in my pocket. I had shorts on so the phone was on the side of my leg. I landed full force on it, thankfully, and didn’t get my leg ripped up. The plastic part of the case did break, but the phone and I were fine.

Also they have a good lifetime warranty if it breaks. Paid $10 for the shipping and handling and got a new case mailed to me when my old one broke from the fall on ice.
