great case!
Color: Navy Blue
pros; the color is beautiful. I picked the navy blue. It is exactly as the description described. It goes very well with my blue iPad. The size is very precise and fits perfectly on my iPad. The magnet that holds the case together is very strong. The iPad itself can pivot vertically and horizontally using that magnet. This works very smooth. The magnet closure for the case itself is strong and holds well. The magnet that holds the keyboard in place also works very well. Cons; when the keyboard is in its correct position, it is difficult to angle the iPad in front into the provided grooves. The keyboard gets into the way. This prevents the iPad from reaching the grooves provided. The keyboard feels very light and cheap.
The keyboard itself connected with the Bluetooth very easily. It works wonderful. I love the back light on the keyboard. The color of the keyboard is wonderful. However, as I said above, it does feel a bit cheap. But for 20 bucks, what can you ask for.
When the case is folded together with the keyboard in the iPad, it is a bit bulky. But I knew that from the previous reviews and was expecting it.
What I love most about this case is that the iPad can be removed using the magnet on the back from the keyboard portion, but it is still protected by the exterior plastic case. So in situations where I don’t need to use my keyboard, I can remove the iPad itself and know that it’s still protected overall I recommend this product.

Nice Case & Keyboard
Color: Blue
Love this case with a keyboard. I like using the keyboard vs using one on the screen of iPad. And the keyboard has rechargeable batteries instead of having to buy batteries. And it protects my iPad.

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!
