We offered this product to a cousin for her first child, as this product has convinced us since the birth of our children. A little scary to the baby through the snoring it produces in operation, he nevertheless convinced our children when they were old enough to understand the discomfort of full nose, but they were not able to blow his nose alone. Its effectiveness is real unlike other reviews here and there: I think the people involved do not know properly use this baby fly, they imagine or lead a child's nose completely congested. It is not the purpose or the pretension of the device! Just a nose nostril after another by plugging the opposite nostril, optionally by spraying nasal product or a physiological saline dose beforehand to make "the material" and liquefy dust suction. The cleaning of the nozzles and the container is done easily, be careful however not to force to dismantle. Despite their resistance, there is a risk of breaking the integrated suction tube to the device. We never had a care for 5 years, the accessories and supplied tips are adapted and evolve with the size of the child, it just takes time to change the batteries in time. It's silly, but it is often aware of their state of wear that when they are replaced and that the aspiration then finds all its original power!
