The case does what it describes, Smart Cover. I have it for an iPad 7th gen. It covers the screen and also functions as a stand. The magnetic contacts are highly functional.
It is not a bulky case and does not protect the back metal part or the frame of the iPad.
I prefer it because of its weight, as the iPad is already heavy and a full cover case would make it even heavier, thus more tiring to use.
It could definitely be cheaper.

Good and the Chinese are fine, but with so much money you give for the air, it's better for no one to regret the best cover, which is clearly the original.
