The projector functions without issue, but it's recommended for those who can accept the following two points: ① There appears to be a small stain from the time of purchase. ② When the screen is black in a completely dark room, small specks, possibly dust, are visible. Personally, neither of these points bothered me much when watching videos. ※ Photo 4: The area circled with a ⚪︎ shows the stain. ※ Photos 5 and 6: Projection in a completely dark room. ※ Photos 7 and 8: Projection with some light on. This is a 4K-compatible projector with 16,000 lumens of brightness, Android TV functionality, and 270-degree rotation. - Color: White - Resolution: 4K Support - Brightness: 16,000 lumens - Bluetooth: Bluetooth 5.2 - Exterior Damage: Crack on the side - Features: Android TV Functionality - Rotation: 270-degree rotation
