This is some unreal beauty!I really liked it! What a beautiful light it comes from! The radius of bright light is about 2 meters, but you can change the intensity of the remote control. The sensor somehow does not understand while it works for me. Then reacts, then no. I guess I haven't figured it out yet. The lamp itself is made of plastic. Easy. Without a cord-USB is charged. Thats good. I do not like extra cords. And I don't have a outlet where I want to put it. I wonder, of course, how much will grab the charge. Be sure to order more, put in other rooms and give friends!
