Take a standard yo-yo with a 44 inch string and pack it full of electronics, and you get an E-yo. The battery operated yo-yo measures four things: speed, distance (cumulative), average time sleep of the spinning yo-yo and the cumulative number of times the yo-yo is thrown or caught. The toy comes in four colors (black, red, blue and purple). We spent about ten minutes with two different models and were unable to figure it out.
