Using this night light is a breeze. Just connect it to a power source via the USB interface. You can place it on any flat surface in your room to create a cozy atmosphere. When it comes to cleaning, use a soft, dry cloth to wipe the light panel and base. Avoid using harsh chemicals or abrasive materials as they could damage the surface. Be careful not to get the light wet. Also, remember that the color you see might be a bit different from the picture because of your monitor and the lighting in your room. And since it's measured by hand, there could be a small size difference. Enjoy your personalized 3D LED night light!
