I have had my Starkey hearing aids for several weeks now and I am certainly enjoying them They are so comfortable I forget I have them in. They are also very user friendly. I have had no problems changing batteries, cleaning or just generally caring for them. I have the highest regard for David Russo. He is excellent in explaining your needs and the workings of the hearing aids. You will leave his office feeling that he really cares that he is helping you and that you are happy. Thank you David!
