Hey, I'm probably a bit late, but I just saw this thread. My sis just bought that potty for her 22 month DS and the first time he used it, he weeed on the carpet instead of in the potty! I think the bowl is way too small to fit both ends on haha.

I have a sesame street one that I bought from target a few months ago. It's similar to the thomas the tank one, but the seat is soft and cushiony, and the bowl is MUCH bigger. I think it is heaps better. It still has the removable bit for easy cleaning. My DS has been using it since about 10 months, and we haven't had any wee outside the potty.
