### ⭐⭐⭐⭐⭐ Great inexpensive novelty gift.
*by S***R on August 16, 2025*

Amazing to watch. Might even be used as a magic trick.

### ⭐⭐⭐⭐⭐ These are well made and work as intended
*by P***D on October 13, 2023*

I wish that they were a little heavier, but since they are molded plastic, I don't see that is possible. I got these to give away. Great fun.

### ⭐⭐⭐⭐⭐ Neat-o!
*by G***R on December 10, 2015*

These things are way cooler than I expected! If you spin them one way they'll go forever, but spin the other way & they'll rattle to a stop or change direction. I figured it would be a cool stocking stuffer for work, & I was absolutely right. I only wish I'd bought more, I think everyone should have one for absent-minded fiddling. They're not exceptionally useful for anything else but they're great kinetic playthings. The package I received also came with a lesson plan for a physics/science class, which was a really neat addition; it has suggested activities about making observations. Cool toy, even cooler learning tool.
