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

I’m absolutely loving this iPad case with the wireless keyboard and mouse! The first thing that caught my eye was the gorgeous glittery blue color — it looks so stylish and unique without being over the top. The case feels sturdy and protective while still being lightweight and easy to carry. The keyboard connects quickly and types smoothly, making it perfect for work, school, or just browsing online. The wireless mouse is a great bonus and makes using the iPad feel much more like a laptop. I also love that the stand holds the iPad at a comfortable viewing angle for typing or watching videos. Everything charges easily, setup was simple, and the battery life has been great so far. Overall, this set completely upgraded my iPad experience and looks beautiful at the same time. Definitely recommend if you want something functional, protective, and cute
