I tried it on the iPad Pro 11. There is a slight difference in thickness, but it does well.
Closing the keyboard cover doesn't turn off the screen.
I am also satisfied with the keyboard key. I can buy it at a price of 20,000 won, so I'm really satisfied and it will be a shame if it fails, but I think I will buy it again.
I purchased a similar structure of Logitech keyboard in the middle of 100,000 won, but after 2-3 years, it fails every time. Now, Logitech products are at a loss because it is not.
