From the Duncan website:
"The ORB is the best-playing light up yo-yo in history. With multiple LED's in random colors, The ORB gives a spectacular light show. The ball-bearing transaxle gives long sleepers, while the adjustable gap lets you tailor the performance. A unique motion-sensing switch keeps the lights going as long as you play, but turns them off 45 seconds after you stop. Long-life batteries ensure hours of fun. Heavy-duty construction means this light up yo-yo isn't just a light on a string - it's a high-performance yo-yo that lights up."
Came with extra black string and four "button" batteries for the LEDs. Also, the yo-yo was made in China and the string was made in Taiwan.
