Since it comes in here all the reviews always the same misjudgment, here an explanation: The Goldi cleaner should cover the nose of the infant (in part). That's why he has the vent holes. The background is that an infant during breastfeeding also pushes the nose to the chest. That is why here the greater calming effect, as with all other suckers. To the weight that the fall out of the nipple favors, too, is quite intentional because a continuous sucking is on the jaw, satiety, and due to the risk of nipple confusion (which I personally consider to be unscientific humbug) does not make sense. This can be in favor or not, but it's not bad design. Why I disconnect a star? The suction stuck so strongly after 1 month use that he instantly is breaded in dirt and fluff when it falls out of your mouth. I can not imagine that the intent is to me.
