Get one!
Color: Peacock Blue, Color: Peacock Blue
Very nice IPad case. It fits really nicely. It took a while to get it setup because of how well it fits but it is well worth it. I love the he fact it uses magnets to position the screen instead of tracks. Stays in place while working instead of slipping throughout the day. I would and will recommend and buy again.

Works Perfectly for 2025 Apple iPad A16
Color: A-Navy Blue
I was super surprised that the entire case had protective plastic to keep it scratch free before use. I bought it under $20 which is a really reasonable price. I wanted a hard case that could be angled in any which way I needed. I wanted it to be able to be used on a desk, table, my lap, and even in bed. The one major thing that I looked for was it's front cover display to use be used as a stand. A lot of cases use the inside of the cover to be placed face down on surfaces, which in turn, collects debris and other unwanted nastiness. Rarely can you find something as simple as that on Amazon, ironically. I tried it on the table and the magnets are incredibly strong. I lifted up the entire iPad and the front cover stand stuck together. It takes a good amount of force to adjust. That was a massive surprise and major benefit of getting this case that wasn't advertised. I don't care too much for the Apple Pencil holder on the top and feel it's an unnecessary feature. I use my iPad as either an extended display for workflow or just to watch movies, play games, and surf the internet. One of the things I did was remove the screen protector which was super easy to do. I don't need it since I already have a screen protector installed. Installation was super easy and removing the protective plastic was satisfying. The rubber is malleable enough to where it feels sturdy, but it allows installation to be simple and easy. The frame is nice and thick, alongside the protective cover. I have full confidence that if I dropped my iPad, it will survive without issue. I'm not concerned about the color, but it looks as advertised in the photos. I bought the blue one because it was the cheapest one and it ironically matched my blue iPad. Overall, and excellent purchase for an excellent product!
