Thank you for your responses. I ended up buying it, and it has changed the way I use my iPad.
I don’t notice any light bleed when the iPad is stationary or pushed open. The only time I see any light bleed around the hinges are when I push it closed. Once I stop pushing, there is no more bleed. I’ll just have to keep an eye on it.
But having said, that I’m very pleased with my purchase. I was hardly using my iPad mini 5 before, but now my laptop stays hooked up to a monitor and my iPad is my go to device for portability.
