This is a very cool lamp, looks very cute. Well illuminates the room, works both from the sockets and from the batteries. In the kit there are replaceable slides and wire. Button a switches light, warm, cold, blue or all at once. Button b includes dvision and adjusts brightness. If you close the cap turns out a night light, not very bright. All this came in 6 days in russia. Everything is fine) it's been a few days and it still works.
