Really anti-climatic and difficult to clean up
I found this to be shockingly boring. It does much less than kinetic sand (and is much harder to clean up as it doesn't stick to itself).  You smoosh it into a little ball and then the ball expands a bit.  But that's it.  There's a lot of different kinetic toys and this is my least favorite.  It isn't really moldable; it doesn't feel great. I really don't get it at all.
