I typically never write reviews. I had to sit and write this one because of the miracle that has happened as a result of using the Navage system. I experienced tons of mucus and phlegm around my vocal chords which for a year has meant the loss of my voice. I went to an ear, nose and throat doctor and he had placed 4 needles in each of 4 polyps to tell me they were not malignant. They also checked my thyroid - no problem. For a year, my voice would crack, squeak and give out. I tried everything. Herbal teas, apple cider vinegar, ginger root, lemons and honey, a humidifier... everything. The collection of mucus around my vocal chords would cause my voice to squeak. In desperation I purchased the Navage system because a sinus-wash system seemed to give some relief. After pods, I was shocked to hear my voice in recovery with a reduction in the mucus and phlegm in my throat. I was even more shocked to see the particles released in the saline. Navage works!!!!!!
