I got this to replace an old iPad Pro. It does everything my old pro did, except for having a smaller screen. Good value and set up and migration from old iPad was super easy. Good battery life and so far playing games on it haven't been an issue

Nice size with a nice clear picture. Replaced a very old iPad. Not all apps and things transferred like the iPhone. But very manageable with a little time. So far I am pleased with this iPad.

Its Great! Except one tiny detail

Ipad works great, easy to set up and everything transferred from the cloud from a backup I had (thank god because my other ipad is completely dead). Everything is in order except they put the magnets in the wrong spot xD. It doesnt matter functionality wise and I feel its more hassle to exchange than its worth so I am going to keep the iPad. With the case its in it doesnt really matter because theres a spot already for the pen. 4/5 stars

Great iPad, so much faster and stable than our old one (5th generation). Totally worth the price to upgrade.

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.
