Both workers and arrived without any chips or defects. Included USB cord, when connected while charging the moon shines red when charged blue, but only at the plug in point. Standalone, without cord shines white or yellow light, evenly. The moon is better for decor and night light than it is for reading. You can read with it but not comforably. How long the charge last we will wait and see, but for some reason one moon charged quicker than the other.
