Query: Leave a ring of pee.

The seat is inexpensive and soft. Also easy to clean. But it has to be cleaned every time its used, as well as the regular toilet seat underneath. It leaves a ring of urine around the regular toilet seat almost every time. Cleaning the toilet a half dozen times a day is driving me crazy. Maybe if you have a girl, this would be an okay seat, but not for little boys, even when they "point down" as best they can.The bjorn seat is more expensive, but definitely worth it.
