Again? If this is directed at me, I’ve never started a debate about Costco or anything else. In fact, I posted about my positive experience at Costco within the past month.
In my experience, the key ingredient in treating hearing loss is the professional providing the treatment. The hearing aid is simply the vehicle by which that treatment is delivered in the case of hearing loss. The level of training which an HIS receives is far less than what someone who is generally considered a professional receives. I thought it was important to state that for the record. When you buy at Costco, you are buying a service delivery model, not just a device. The actual audiologists in the Costco service delivery model are few and far between in my personal experience.
