The Ram is extremely secure. I've flipped over handlebars, broken my collarbone and ribs, w/ nary a scratch on the phone, and it never pops out. Two drawbacks: not weatherproof, and you can't use a bumper case.

I was just about to order the LifeProof, but the quadcase looks better, less clunky, easier, and cheaper. I put my name down on the wait list.
