The kraken case has saved my phone from falls on all hard surfaces that crack iPhones; tile, concrete, wood, stairs & gravel. Portions of the kraken case have cracked off bur it remained intact.

My phone has gone from the kraken to the taktik case.
The only problem or difference I noticed is that on the bottom of the case are the sound ports for the speaker- cover them with your finger or article of clothing and it totally muffles the sound. I would suggest putting the phone in your locket upside down to ensure you can hear it.
