This is not a complaint but a balancing statement. I'm on my third set of Costco hearing aids and getting ready to buy the fourth pair (for $3000).
My first audiologist retired, second one transferred and I dumped the 3rd because she didn't listen (ironic) and went to a different Costco. The audiologist there is great, works hard to adjust the aids to my hearing needs and makes sure I'm taking advantage of all the perks.
Audiologists are not all equally competent, whether it's Costco or someplace else. Find one that will take care of you and focus on what works best for you and not what the charts tell them to do.
Reason of review: Good customer service.
