[Q]: My kids have about a dozen spinners, a couple classic style like you get at any store, some with lights, a couple different shaped ones, but none that were metal. This has a bit of weight to it and feels great in your hand. We haven't tested it but it seems like this one spins a bit longer than the plastic ones. I'm guessing there's more momentum because they are heavier, either way it works great and my kids love it.

positive
