This review refers to the nasal douche, to nasal rinse I can not comment yet. The nasal douche served its purpose, but in my opinion is processed deficient. You mus press firmly during the entire flushing process on the "button" to keep open the valve. The "Olive" you can only with difficulty "open" or "close". Otherwise, the nasal douche OK, except that due to the poor design and there is still some water inside.
