When I ordered them, I was skeptical of course. I mean,I had purchased hearing aids twice before, and they didn't stand up to the quality I had expected. Plus, they kept falling out of my ears. I guess I have small ear orofices. But. I didn't want to get them from an audiologist and have to pay $5,000 either. So, I gave it one more shot, and ordered from Bossa. I didn't even put them until the next afternoon. I wasn't ready for a third disappointment yet. When I put one in, I couldn't believe it. I can hear! And they fit! I'm very pleased, very! Thank you so much. Sincerely, Judi Miller
