Very cool item, I am giving it as a gift when I'm done playing !

Doesn't work. I returned it, but the second one didn't work either. Would have been cool if it actually worked.

Performance requires charging and sensor button start. Good quality. It was entertaining to watch in use during my sons science fair presentation. Very easy to use once we located the sensor start button. Appearance was as advertised.

I ordered two of these gadgets and took them with me to the east coast to give them as presents. One of them never worked and the ball always missed the bowl. It wasn't worth my time and effort to carry it all the way back to the west coast, wrap it up again and send it back for a refund, so I absorbed the cost!

Three days after receiving it the device would no longer hold a full charge. The ball would make two loops and then the third would fall short, put the ball back into play and the fourth would be even shorter of reaching the goal.
