Clear display
Style: Wi-Fi, Size: 128GB, Color: Blue, Configuration: Without AppleCare+
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

New Ipad
Style: Wi-Fi, Size: 256GB, Color: Yellow, Configuration: Without AppleCare+
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
Style: Wi-Fi, Size: 512GB, Color: Pink, Configuration: Without AppleCare+, Style: Wi-Fi, Size: 512GB, Color: Pink, Configuration: Without AppleCare+
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

Best Kids iPad Case - Durable and Perfect Protection!
Color: A01-Colorful Pink
This BRAECN kids case for iPad is absolutely perfect! The heavy-duty rugged silicon construction provides outstanding protection for my child's iPad. I love how durable and shock-absorbing it is - it has already survived multiple drops without any damage to the tablet. The fun, colorful design is eye-catching and appealing to kids. The built-in handle is genius - it makes it easy for little hands to carry the iPad around safely. The stand functionality works perfectly for watching videos or doing homework hands-free. The case fits my iPad 11th generation perfectly with precise cutouts for all ports and buttons. Everything remains easily accessible while staying fully protected. The material is high-quality, non-toxic, and safe for kids. It's easy to clean when it gets sticky fingerprints or spills. The grip is excellent, making it less likely to slip from small hands. The raised edges provide extra screen protection when laid face-down. Installation was quick and easy. The case adds minimal bulk while providing maximum protection. This gives me complete peace of mind letting my child use the iPad. Best kids iPad case I've found - highly recommend!
