Beautiful, and everything I want it except that the keyboard keys didn’t work😭
Color: Light Pink
I searched and search for the right keyboard case for me. The most important thing for me was to be able to remove the iPad case itself from the whole case and keyboard, and this one was it. Unfortunately, when I started checking the keyboard a lot of The keys were not output in the correct symbol or letters. So defeats the whole purpose of having a keyboard. I returned it and asked for a replacement, thinking that the item was defected, but when I got the New replacement, it was the same thing so I tried to contact the seller, but there was no option to do that. Therefore, I had to return the second replacement keyboard and look for another keyboard cover.

Quality and Functional
Color: Navy Blue, Color: Navy Blue
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!

Quality Case
Color: Pink
This is an All in Pne case. I really like the lavender color with sparkles. It is a little heavier than expected but I still love it!
