I have had the exact same experience. No bends. Phone is flawless. People who are being their phones have to be doing something to cause it. My iPhone wasn't made especially for me with different materials, so it isn't any stronger than anyone else's.
Stop being careless and stop bending your phones.
Oh, so since yours didn't bend, then other people are being careless?
Believe it or not, but you do not represent everyone.
