The product picture is wrong so unfortunately. The cover is clamped at the corners. On the side of the key, it is open. The fit is excellent. By Cover the Lumia 720 is even better in your hand when it operated with one hand. The coil provides natural that the smartphone is much more difficult. (Chill the shell weighs almost as much as the Lumia itself.) But that really makes me not something out. The advantage of wireless charging, it is worth it to me.
