Received ny order within 5 days. Tried it, not sure it works. The light are too bright, but bcos no instruction, not sure what are these 3 lights mean for. There's a button on top center, when pressed on it, the center blue light is off, not sure is it necessary to have this blue light on? Cos blue light is too bright. No choice, i use a sticker to cover the blue light.Mar 01, 2019
