Product description    Our many studies show that iFace Sensation is different from iFace’s existing designs such as iFace First Class and Revolution. Comparing with previous products, it is designed to have a thicker urethane on the top and bottom. By focusing on the top and bottom of the case with more urethane material, the center of gravity will allow your phone to be predictable in dropping either two directions - bottom and top side of the handset. At the same time, it provides outstanding grip with its slimmer and lighter design than existing iFace cases.
