The CIRC-CASE offers reliable iPhone protection for the average clumsy user. It is stable, light, flexible and, naturally, not quite as secure as a giant safe. We feel that any information on the safe fall height of these kinds of products is a bit untrustworthy, since iPhone protectors are no different to bumpers, bike helmets or bodyguards: active protection leaves its mark on the protector and can shorten its lifespan. Thats what it's there for, so we can only ensure a limited lifespan for hard plastic cases. We encourage you to furtherly protect your device a screen protector.
