Cute but beware of buttons with a mind of its own.
Color: Pink, Color: Pink
Super cute. Only has 3 keyboard multicolor options and one white light setting. Dimmable. But its functionality needs work. But the keys keep doing weird things like skipping lines, changing excel sheet formatting and just moving where I am typing on it own. Like it will be typing and then move to the beginning of the sentence and keep moving. The feel is super light and the quality of the case is great though. It’s easy to use and install to device with Bluetooth. Value is you get what you paid for. This keyboard is cute but not working quite well. I accidentally ordered a different model for a later iPad and had to return it, but based off of a leader model in comparison to this one, the keyboard just isn’t that great

Great Keyboard Case!
Color: Pink
Bought this for the wife for Mother’s Day since she needed a new keyboard and case. She used my old Magic Keyboard but constantly was tired of taking her iPad off, just to rotate it. Bought this and she loves it. Very durable, even with our 2 year old playing with it. Keyboard is bright and is good to use.
Just a Bluetooth keyboard setup and it’s all good to go! Definitely great value for the money and something highly recommended for those with an iPad Air or Pro.

Super cute and soft!
Color: Pine Green, Color: Pine Green
I really like this case. I was surprised by how soft it is! It arrived in perfect condition (just like the photos), no smell, keyboard worked. I followed the sellers instructions to charge before use. I gave it one less star because personally don’t care about the keyboard, it’s a little on the slower side when using the mousepad or typing. I didn’t have any issues with connecting. It was an easy setup. I’d suggest you spend the money for a laptop or a true keyboard if you need it. This is more for looks. If it wasn’t for the quality of the case, I’d probably return.
