Cheap and good
Color: Black, Color: Black
I chose the color black and it gives a really nice look, especially with the multicolor led lights around the keys. It is very easy to clean and you can shut off the keyboard to prevent any mess with the iPad. The magnet is very nice and keeps the keyboard in place. The keyboard doesn’t easily slip or anything so it holds the iPad very well. Only bad thing is that over time the iPad begins to scrape off the pain and it leaves your keyboard with some white spots all over :/ but if looks isn’t something that you care about, this is the keyboard for you. Don’t use it for gaming because there is a delay in functionality when you press a key and then try to use the pad. Also, you have to press the keys a bit harder than the usual keyboard. But for the price? This is a great item! Definitely worth my money

Works great
Color: Purple
Works just pretty good. My only complaint would be that it can turn on the screen when closed. I put it in my backpack and went throughout my school day only to find out later the battery had drained because the screen would light up and stay on. Did not have this issue with other covers. Easy work around is to just do a complete shutoff or maybe change the settings before putting in away. I just had the habit of keeping mine on because of frequent use in back to back classes.

Great case & keyboard combo

Great case! Updated my son’s children’s case to this one and he loves it! He feels like it’s a laptop now. The magnetic feature is great & it’s super easy to install!

Cover is nice, keyboard could be better
Color: Navy Blue
The cover itself is nice. The magnetic closure works well. It fits my iPad really well. It’s a good case for the money, but the keyboard feels pretty cheap and flimsy.
