Whatever you do please don’t use this service. These guys will try to rip you off. My elderly mother got my niece to bring her there to inquire about a hearing aid and the next thing we knew she had signed up for a $ 5000 hearing aid. My 45 year old niece said that they would not let her go to the back to discuss the purchase with her and kept her isolated until after she had signed the paperwork. I would suggest if you really want to get a quality product to go through a referral from your doctor… with a degree. In order to sell hearing aids at ME you only need a high school diploma.
