"A native 1080p display for under $100, if you can live in the dark."
The 'Native 1080P' spec means the projector's internal panel has 1920x1080 physical pixels, ensuring a sharper image than projectors that just 'support' 1080p. This guarantees resolution, but says nothing about the critical factors of brightness, contrast, or color accuracy.
This is for someone who needs a cheap, portable display for casual, temporary use in a pitch-black room. Consider it for a kid's bedroom movie night, a dorm room, or projecting holiday decorations on a wall, where performance is secondary to price.
Anyone seeking a primary display to replace a TV or for use in a living room should skip this. The unstated (and certainly low) brightness will be frustrating in any room with windows or ambient light. Users sensitive to image quality will be disappointed.
