"A functional toy projector, provided your expectations are as low as the price."
The 'Full HD 1080P Support' claim means the device's input can read a 1080p signal; it does not project a 1080p image. The actual on-screen picture is a much lower, non-HD resolution.
This serves as a novelty for a child's bedroom or a single-use party where a large, dim image is better than no image. Its only compelling feature is the sub-$50 price. It is a disposable electronic, not a home theater component.
Anyone seeking a true HD picture, the ability to watch in a room with any ambient light, or a simple plug-and-play experience with streaming sticks. A used, name-brand 720p projector represents a far better use of funds.
