The simplest and ultimately the best! Easy to clean (think about removing the plastic segment in the head of the tip), soft tip for beginners and especially no suction loss (I tried it with a pear between the tip and the tube but I had to suck like a beast). In short it has become my favorite object with a handle 3 bronchiolitis in winter. The inventor deserves a Nobel Prize. The most difficult is to understand that it's a baby for her own good!
