I have one. It's ok for little baby. The fun things of this 廁板 is its major problem. My son just focus to press the different buttons for music and flush toilet sound, and also ride it like a rocking toy. For best toilet trainning fuction, I buy a plain 廁板 to put on an adult toilet bowl to train my son. Maybe he think that this one is similar to daddy and mammy's, so he learn very fast.
