This is one of the best toys that I have ever seen.  I have got this back in 2012 and it still works great and my kids still use it (they are 2 and 5) I have a lot of play dates and everyone is always asking me where I got this toy.  They put toys on top of the spinners and watch them go round and round to they stack them up to see how high they can get them to go as they go around.
