Costco will screen you and set you up with what you want (they have other brands, including Phonak, if you want to spend the extra money for the same thing).
I went to three audiologists with dismal results. One of them was actually honest and said point blank: "I'm here to sell hearing aids".
I did get a pair "on trial" from one of them. I hated them and returned them, however I was $200.00 poorer for the experience. Not one follow up was scheduled or recommended by the audiologist.
I went to Costco where they tested me and fit me with the best possible devices. Follow ups we're automatically scheduled and any servicing is free of charge no matter how many times you bring them by. My hearing consultant with Costco was superior to any of the three audiologists I went to.
Go to Costco...you will not regret it.
