I had bought these trainers because he is high enough for our toilets seemed the only, unfortunately, the amount is still marginal. Then I had hoped that our son now 3jähriger thus alone could go to the bathroom - far from it, he has the seat more problems than no seat only with a stool to climb. The "leader" is so shaky that a child with his pants can not climb up to but pull down the pants on the ladder, the steps are too shaky. On top of that loosen the screws that hold the seat with the head, constantly, when there is a completely dissolves, the part is even dangerous.
