Then I exploded with laughter the first time that my child peed in this jar and the music went off. It surprised him and he almost started jumping :))) Otherwise, after 6-8mois of use there are false touch. Also having a lambda pot (my son chooses himself in store), I can tell you that it uses both, even a little one he chooses himself ... In short, it does not worth the shot put 50 into a pot while 10 are sufficient
