I was looking for a case that could rotate and includes a keyboard. I have the gen 5 Ipad Air and it fits just fine. The part that rotates is magnetic (pretty strong) so if i just want the part with the ipad, I can just take it off. Keyboard is magnetic and the touchpad is such a bonus. It was easy to connect and every key works (can also change light color). Im also really impressed with the quality of the case, its pretty thick and even the plastic is nice. The navy blue color is also super cute, wish they had a dark red color too.

ABSOLUTELY PERFECT - I LOVE THIS!!!

Color: Pink

I absolutely LOVE this case and the keyboard - it’s absolutely perfect in just about every way. If I had to get nit-picky and find something to give feedback on, I would say it is a bit heavy and it is a bit annoying that you have to move the keyboard forward when you want to use it and backward when you want to close up the case but I don’t care, I love it!
