My husband got one for each of our boys, despite my initial reservations. However, I'm so happy he did! I hate dealing with slime with a toddler, but this stuff is amazing. It isn't runny or sticky, and it didn't leave behind any residue on the kids or the table. Plus, it smells *amazing*, and the mix-ins are adorable. We'll worth the money. My only complaint is hubby didn't buy me one.
