I like my Phonak Nadia hearing aids when they work. But, every 2 – 4 months one of them clogs and they have to be sent back for repair. I change wax guards every week. I clean my ears with hydrogen peroxide once a month, I brush and wipe the aids twice a day. I use a nano-thread-wipe (forget the correct name) to clean the air vents every morning. All this is to no avail. I know of one other person that has suffered from this with Phonak. Anyone else? I have renewed my warranty twice and Phonak graciously gave me 6 more months. Now I am at the end of the line. Soon one will clog and I will have to pay a few hundred dollars every 2 – 4 months to get them repaired. That will be at least $1,000 a year. I guess I will need to prepare for new aids soon. What is the best brand? My brand before was Oticon and they were excellent, but they died after about 6 years (I got them repaired and they remain my back up! Yay!) Is Oticon doing 'Neuro-technology? What is the best brand?
