I am a fidget lover and have made my own spinners in the past. I also like to play with magnets, so that was just right. My wife bought this on a whim and I was a little excited to try it, but the magnets are MUCH weaker than I thought. If you rotate them like in the picture they just fly - they are not strong enough to hold together under any centrifugal force. Even just juggling them in my palms, I felt like they might just be three loose bearings for all the magnetic attraction they had for each other. I played with it for the full 45 seconds before handing it back to my wife and saying thanks but no thanks. Overall a good idea but I would recommend stronger neodymium magnets inside.
