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

Sturdy
The case is pretty substantial. The color is nice and I love that you can swivel my IPad for viewing. The only thing that I would change would be to have the pencil holder be removable or let it fold back if you don’t need it.
