ARTlii Projector - Brand: ARTlii I purchased this a few years ago and used it once. I believe it works without any problems, but I don't have the manual. I think I bought it on Amazon, so you might be able to find it if you search there. The ceiling in my room is sloped, so it's become difficult to see the projection. The projector makes a characteristic sound while it's running. It's not broken. Price reduction possible ⭕️ Thank you for looking.
