Great fun protection!
This case gets used.. more than it should. Stand is still working great. Coloring is definitely tinted a bit but it still looks good on a gen 10 iPad.

Weak penholder/only 1 stand position
I got this case for my iPad I use for medical school and it fits great, no issue there. My only complaints about it are that the Apple pencil holder slot doesn't have a great hold, which is fine if your device is mostly stationary, but I worry about losing the pencil in the future when walking around at clinical rotations. They should have put it on the other side of the device where the built-in magnet is so that there was some sort of internal holding force while not making the case any more bulky. The kickstand has a nice hold when locked into place, but there is unfortunately only one angle that it does lock into place, all others it tends to slide sometimes.

Great protective case with a sleek design
Color: White
This iPad case fits perfectly and looks very clean and modern. The clear back keeps the iPad visible while the frame provides good protection around the edges. The case feels sturdy without adding too much bulk. I really like the built-in pencil holder—it keeps the Apple Pencil secure and easy to access. The auto sleep/wake feature works well, and the cover folds nicely to support different viewing angles for typing or watching videos. Overall, this is a great quality case that offers good protection and functionality. I would definitely recommend it if you’re looking for a simple, protective, and well-designed iPad cover.
