I have one of these. It's only 'ok'. There is significant ghosting and it's not very good when the scene is dark, but it's much better than my BOOX tablet. I just got it so I'm still experimenting with different uses.
It functions like a normal monitor. It connected to my Macbook air (M2) and Windows machine without installing anything. It has a USB-C video port, but an HDMI->USB-C converter works too. It has an 1872x1404 (4:3) resolution, which is why I used Miami Vice for the video. It would not connect to my PS5, which I think comes down to the PS5 only supporting 16:9/21:9.
Here's a clip of it playing video: https://youtu.be/povlk3hKTVA
