This vacuum cleaner attachment is really useful. It works flawlessly and is extremely effective. However, I have a bad conscience when applying. When I turn on the vacuum cleaner, and our small skid with the nasal aspirator to the body, it has the fear and panic written on their face. The vacuum cleaner sound, which additionally strengthened when some snot already been sucked in the tube and depends, however, seems a bit scary. Impractical I find the product, especially at night when everyone is asleep. Build and make noise with the vacuum cleaner makes you look at the rest of the family at night not very popular.
