In general, the idea is quite funny: child sits down, does his business and is rewarded with Fanfare and / or applause. Although is a bit silly, but children laugh piebald. Since the pot is to be used as a stool or step, it does not take up unnecessary space in the bathroom away, because you need to anyway.
The removable tray is unfortunately a bit small for large "pile (if one can speak in three years of it) will get tight. And they can be difficult to clean, especially where the sensors are in the pot. And this is a real disadvantage.
In short, stable, well-designed product. Thumbs up.
