This gadget is power directly by the USB port on your computer, it has disco lighting and motorized action. She can dance to her own music, or you can plug in your own audio player and she’ll dance to the rythm of your own songs. Did I mention that she’s not expensive either ? The cost of this Cables Unlimited USB gadget is only only $25 and if you like it, you can get one from Amazon.
No extra batteries or software is needed in order to see the dancer do her thing.
