As to be expected from a low ANSI projector, it works well in fully controlled and dark rooms. Based on my testing, the best distance is 100 inches, which projects 80 inches in a completely dark room. It can also project up to 120 inches by 150 inches, but it's a little hard to see when the scene is dark. In a room with the lights on, the best screen I can get is 18 inches by 20 inches. I also noticed that the built-in YouTube can produce a brighter image than using a Fire Stick. I have tested other advertised features and they work. I can easily mirror my screen from my phone and the casting works too if the app supports it. There is a surprise about the speaker, it can play stereo sounds and the sound quality is good. What I meant by good is that the voice is clear and the bass is adequate. The quality is even better than some cheap TVs and Bluetooth speakers. Auto keystone correction works vertically but may need to be reset each time the projector is turned on. In summary, this small projector can serve you as a portable projector and create a big screen in the dark. In addition, it comes with a small tripod, a remote control and a carrying case, so you can easily take it with you when you travel or go camping. As a $200 projector, I think it's good for its purpose. If you intend to use it during the day or with the lights on, you may need to consider a much taller ANSI projector. Attached are 2 pictures and they had a screen size of about 120 inches.
