Has anyone used this product. I am thinking of purchasing one to nebulize pulmozyme through nose, and even Tobi when PA is cultured. I do not feel chronic sinusius is given enough attention to in CFers...but is just as impt to focus on. I'm beging to think that some cultures of PA are not from the lungs, but from post nasal drainage of PA in the sinuses. And if you only use the mouth piece nebulizer when u r doing TOBI, then it really is not getting up good into your frontal sinuses.
