Case Closed……
This is an excellent case for the current version IPad. It offers excellent all around protection. Additionally, the case has a built in spot for the IPad pencil. The yellow case matches the yellow IPad beautifully. But one of the main reasons for purchasing this case, is how readily it switches from landscape to portrait…… Do not hesitate on this one. Give it a try!!

Durable & protects well
I’ve had this case for a few months and it is holding up great. It is bright and easy to distinguish from other tablets & devices in our home. My iPad 2025 snaps securely in place. I have dropped my iPad many times and this case has protected it every time. I love the rotating feature of this case as well. I highly recommend this brand in whatever color you decide
