The tablet adapts well to the back cover, no worries on that side. However I noticed two drawbacks, the reliefs for the flap is not important enough ipad holds only on the last two positions, the first position (the inclined) is unusable in landscape mode, it's a shame because for me it is the most interesting, the second disadvantage is always on the flap, there is a strong petroleum odor (which fades over time but one that is very unpleasant at first. The ring rotation works well. The price is also attractive. Damage to the two drawbacks.
