I ordered 2 of these.  I bent the clip on mine the 2nd day I owned it, and I use it on a belt.  My wife uses hers to clip on the edge of her pocket and the clip wasn't strong enough to hold.  Neither case would hold a Samsung S3 with a cover on it, and I'm talking only a MyBat cover, not one of the bulletproof Mil-Spec ones.  If you're using a smaller smartphone, or don't mind removing the protective cover, it would be an OK case, but even then it would have the crappy clips.
