I won this at a Christmas bingo game the year before last, but I don't know how to use it... (especially since I didn't have any plans for a Christmas party) I've only turned it on once. Here's the product description I found online: "Along with the Christmas song 'Jingle Bells,' the mirror ball on top automatically rotates and illuminates the room with colorful lights. It runs on 3 AA batteries (sold separately). This product is a decoration, not a toy. Avoid continuous use for more than 4 hours. The size is W75 x D65 x H155mm. Great for store displays or anyone planning a party, what do you think?"
