On the whole this is great, my little girl (17months) loves it and understands what it is as we always call it her toilet rather than a potty.
It's a good height, stable and appears comfortable for her. It is easy to empty and useful to be able to close the lid.
The only minor problem is that if baby sits on it with all lids down (ie in stool mode) she can accidentally pinch the back of her legs if you haven't ensured the lid is completely snug - this happened to our girl. It just requires supervision to ensure the lid is correctly placed when in the down position.
Despite that, it's a great potty, and aesthetically pleasing enough to leave in the lounge, or other public areas if required.
