As a gift for the child of a friend Päärchens I chose this teether after a long search. I wanted something that the child does not hurt and have bought extra me about an issue of eco-test! This Berißring cuts in the 3 categories: ingredients, practice test, additional defects anywhere "very good" and is tested at 14 articles in the top three! And what can I say, he is doing what he should, and the little there is fun =) Any time!
