I haven't used it much, and it's been stored away. The main unit is clean. The first photo was taken with indoor lighting on. In my subjective opinion, the colors look quite vibrant when it's dark. It can also play videos from a micro SD card. Built-in speaker. Operation has been confirmed. The remote control also works. No box. Everything in the photos is included.
