The magnet does not stick to the refrigerator as advertised.. UPDATE ( I love it and it does stick)
Color: Pink
Although it is a nice case, it seems sturdy and it is very beautiful, my main reason for purchasewas I loved the fact that it sticked to the refrigerator. I was very disappointed to see that it does not. It’s too heavy, and it immediately begins to slide. That is the reason why I could not give it more than three stars. It disappointed me enough to where I’m really considering returning the item. UPDATE: I found out how to make a stick to the refrigerator and I absolutely love it! I changed my review and my stars! I’m really happy.

Great Protection, Great Fit — One Small Flaw
Color: Forest Green
I really love this case. It protects the iPad well, fits perfectly, and is still easy to put on and take off. The pencil holder is especially nice — it keeps the Pencil secure without feeling loose or flimsy. My only complaint is that some USB‑A to USB‑C adapters don’t have enough clearance to plug in. The edge of the case blocks certain adapters from seating properly. It’s the only issue I’ve run into, but it’s worth mentioning if you rely on chunkier adapters. Aside from that, this is an excellent case and one I’m happy to use every day.
