She took for my daughter who goes to kindergarten and often suffer from rhinitis. After two weeks of use I can say that all our rhinitis and failed. In my experience I can say that with the help of this tool, not stagnant mucus in the nose, but it turns out, that is, the child can completely blow your nose, it is very hard for children. The tool does not bake does not cause irritation or dryness of mucous membranes of the nose, works very gently. The child becomes easier with this tool, but it is not a vasoconstrictor, so when heavily blocked nose, I think, can not break through. On the effectiveness of work in the 4 because it does not completely lost our rhinitis. For the price a bit pricey for 15ml
