My son is almost three and is being VERY stubborn with potty training. He knows where it goes he is just in this power struggle with us. This was my last resort. Pros: He actually used it to go pee. Cons: The button is way distracting, although he did use the potty I can see this would be a large negative down the line; Too small, he's almost three and he had to sit very far back to feel comfortable on this. The pee guard DID work though when his tush was sitting on the seat correctly, he apparently just didn't like that. If this were slightly larger I'd be enamored with it.
