Ceiling projector set compatible with Chromecast and Fire TV

This is a set for projecting onto the wall near the ceiling.
Are there people who think, 'I wish I could have a screen around here while lying in bed,' when they have a white wall near the ceiling? lol
I was able to comfortably watch videos on the wall at the upper part near the ceiling as a screen while lying in bed.
However, I am selling it as a set because I can no longer use it after moving. I will send it as shown in the photos. Please note:
I cannot guarantee operation, so I am selling it at a low price.

I think it's a good deal considering the total cost.
