The casing may only slightly protect the mobile phone because of its physical design, but you also do not ruined the feel of your phone. This is through the sheath "skintight" practically not greater. The lightly textured back makes the phone a slightly higher grip strength than without shell; but you should not expect too much here. From the front you can see practically impossible that a cover protects the mobile phone, because this is only about 0.2 mm thick and the cell phone tightly encircles. All connections are exposed.
