Query: Simply didn't work

I'm hardly a yo yo pro, but I could definitely throw out some decent tricks back in the day! 'Santa' put this in my 9 year old's stocking and after watching him 1) try to wind it for 5 minutes, and 2) try to get it to come back up to his hand, I finally had to intervene. Uh... yeah, it didn't work. AT ALL. I got it to come back up once or twice, but for the most part you just throw it out and it stays out, then endlessly spins like the string was wound/twisted up. Ok... so I straightened the string until the yo yo hung perfectly straight, wound it up perfectly, threw it out for a prefect watch-how-the-pros-do-it moment, and... nothing. Frustrating for all, total waste of money. Will tryYomega Power Brain XP Wing Colors May Varyand see if we have better luck.
