Negative Positive
Title: Nah.
Review: Not impressive. The torque isn't very strong, and the spinning doesn't last long enough. Back in the early 1970's, there was a toy top called the Whizzer which was nearly more effective than the Powerball. For one thing, it was easy to spin, by rolling it on a tile or concrete floor. Plus it did have torque. The Powerball requires a string to be wrapped around it and pulled, and in my opinion, you get more exercise pulling the string than using the Powerball! Anyway, my advice is to save your money.
