For my new iPad Air 2, first I was trying some cheap case. Well, cheap is cheap quality. Then I Decided to buy this AnyAngle, from good brand. It looks nice for the different angles and it works great.
Just be aware of the weight! 342g to add on your iPad 440g.
I returned it and I am looking for a light one, with less feature. (Most of the time, I hold my iPad, so I prefer a lighter case, even if it's not standing well on the table)
