Does anybody know if any organisation or body has done quantifiable tests on iPhone cases ? My daughter is threatening to buy herself an iPhone 6s and has asked me to buy her a good case for it as a Christmas present. She says that it doesn't matter how big, so as it works. Now personally I think this phone has as much chance as a wineglass in a cement mixer with her but to give the thing as much protection as possible ..... anybody know what will work best ?
