Here’s the thing. Real hearing aids come from one of the big six companies the make HAs. The Costco HAs come from those companies, not some fly-by-night “chinesium” outfit. The difference is model and markup. The Costco people don’t work on commission. They show up to work, presumably to help people. If they can help your dad, then it is worth checking out. If you don’t like them, everything (including the membership fee) is refundable. I think just not molds if you need molds. They would probably be able to refund those too, if you ask nice. For six months trial. Only better deal is the VA. (If he’s eligible, that’s a no-brainer.).
Seriously, the rapport with the HCP is critical. Focus on that.
