The G-Form 'Extreme' cases are also capable of letting the iPad survive from being hit by a hammer or run over by a car! The case can absorb 90% of pressure and can stiffen on impact. The material the case is made of is used on athletes for body protection! It can be used as elbow and knee pads, among others.
While it seems rather excessive, it seems there are enough people that are worried their iPads might be hit by hammers to justify creating this problem. We believe it should be the least of their concerns. Would you ever buy such an excessively protective case?
