The full cover of the ipad affects the heat dissipation, and the shell mainly increases the weight and thickness of the ipad, and also affects the feel of use. In fact, personally, there is no need for ipad film and shell, on the road with a shell can also be added, there is no need to add when using. The screen of the ipad is still relatively hard, and the general use will hardly cause any scratches that affect the visual experience, at most, some particularly small marks do not affect the visual experience.
