Everything is just right. The price is absolutely justified and the nasal aspirator is functioning properly. I must confess I had only doubts. "With the mouth suck the secretions from the nose" ... but it was a bit disgusting idea, but .... This is no problem with this sucker. You can determine the intensity of sucking itself and thereby react to the baby. The suction is applied to the front base of the nose at the nostril and you just have to suck on the mouthpiece. There is no risk of injury when one sets the thing just before the nostril, it must not be put into it! The tube in which the secretion is simply lands flush and also the small filter is easy to change. So all in all the sucker is absolutely thoroughly recommended. I would never spend money on an electrical part, now that I've tested this sucker!
