Dear Lesa, I want to thank you for introducing me to this wonderful new hearing aid. It is much superior to the other kind that I had. There is no squealing from feed-back, and the quality of the sound is very natural. Most of all, I appreciate the fact that you can adjust the loudness of the reception, and the perception of the various pitches right there in your office. You have been most helpful and I can recommend this instrument to anyone and also recommend your kind and efficient service.
