Does a iPhone bumper protect the phone?

I used to have the Otter Box Defender for my iPhone 5 and have recently switched to a simple bumper. Is this enough protection for every day life? Walking around at school? Also will it survive a flate face fall?

If you drop it on the ground, bumper's protection is very limited, but for everyday life, it's enough.

As a protective bumper it works when it's on your phone but you have to handle it with care when you're putting it on and taking it off. The case has 2 layers a hard plastic which sits in between 2 pieces of rubber.

The hard plastic that holds the volume up and down button as well a the power button isn't very durable so you can't bend the case to much when you're putting it on or the hard plastic will snap leaving just the 2 pieces of rubber to keep the bumper together.

The weakest point on the case is by the 30-Pin connector on the bottom of the case, the plastic there's thinner to allow for the 30-Pin connector to make contact with the iPhone which is where you'll notice the break.
