I had to put up with clogged ear for almost a month. NOTHING else worked. Multiple doctor visits and was given multiple antibiotics, decongestants, and was eventually told to wait it out for up to three months.
After four weeks of hearing loss and pressure in my ear I was not willing to wait eight more when it did not seem to be getting better.
After the first use I literally felt fluid drain from my ear. Now a few hours and uses later I would say the symptoms are mostly gone. My hearing is back and there is no more fullness or pressure. Getting another set for my daughter.
