The Astro Disc has four motion-activated, rainbow LEDs built into the outer rim. Batteries are included and replaceable, and it has an auto on/off switch. The sustainable packaging features a "try me" switch so customers can see functionality of the product, the LED brightness and the rainbow effect before they buy. "[The] patented rainbow LED looks amazing at night," Karlie, in marketing at Buztronics, told TDmonthly. "[The] disc throws great and extends the play time into the night by lighting up." Launch date: July 2009.
