Query: Bought two, both broke almost immediately

These are a great idea, but the quality is really lousy. I bought two tops for Christmas -- one for each of my toddler grandsons. They were great and the boys really liked them. Unfortunately, the first one stopped working about three days after Christmas -- when you push down on the handle, the handle just drops down inside and doesn't spin the top. The second one lasted until about a week after New Year, then the same thing happened. When I was a kid, we had a top (by a different manufacturer) that lasted forever. I think it was still working when I was a young adult -- so there's no reason for these to have broken other than bad quality control. I plan to write to the manufacturer, but meanwhile, I wouldn't recommend spending the money on these things.
