This is the worst potty for boys.It is really small so my 3 year old barely fits on it.He has been forced to urinate standing up (which I guess is best in the long run) because the shield squishes his parts!!!and now he is afraid of getting hurt.The potty is not made well for boys nor does it take into consideration "aim" or lack of it. When my son urinates, if he doesn't get it all directly in the green pan, it leaks from in between the seat on to the floor and in between the base of the potty. This thing is disgusting. I have to take it apart and clean it every single time he pees!!!!Also, the sensor is too sensitive. It sings and says he went when nothing happened.I wish I would have spent the money on a simple potty without bells and whistles. Now all my 1 year old wants to do is play with this nasty potty. I finally threw it away and just let my son use the regular toilet.
