Good protection for my ipad
Color: Sky Blue
Flap to close is magnetic, so it stays closed. Has a spot for the open for the ipad. Keyboard is a handy feature to have, and love that it lights up.

Case quality is great, but keyboard is disappointing
Color: Mulberry
The quality of the case is really great. Plum color is beautiful. However, the keyboard is not the best quality. The keys are not sensitive enough and you can easily misspell words if you don’t click a key hard enough. The trackpad shortcuts are cool but inconvenient since you can turn off the shortcuts. You can turn off the trackpad but that just doesn’t work for me.

Economically priced ipad case
Color: Mulberry
There's absolutely no way you could find a better ipad case with a wireless keyboard for this price. My daughter loves it. I was expecting it to feel a little cheap because of the price. I was wrong, this is a great find... thanks

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
