This is EASILY the worst potty seat I have purchased.
* it fits wonderfully on my standard toilet.
* my son has no problems putting it on (and hanging it back up).
* there is a splash guard
* toilet seat hanger comes included (the reason it gets a single star)
* if he is not pushing his "stuff" downward enough, after he has finished, and the UBBI seat is picked up... there is urine ALL over the adult seat.
I have not had this issue with various other seats I have purchased.
