Just for giving you misinformation that the Philips Hearlink 9030 is “exactly” the same as the Oticon More 1, I think you should not choose that Costco fitter to give you support. If they’re ignorant enough to make such an outrageous claim without knowing all the facts, I wonder how good they really are at their job?
That is not to say that you shouldn’t try the HearLink 9030 if you’re curious. If you have plenty of time before you have to return your More 1, and you can get your HearLink 9030 from Costco right away so you can do parallel A/B comparison live, I think it’d be a good idea. Who knows, maybe you’ll decide that for the money, the HearLink 9030 is good enough for you.
Just don’t use that Costco fitter who told you that they’re exactly the same if you can help it. Find a different Costco fitter because you may have a better chance at a more competent fitter who may know better. But Costco fitters do seem to have a tendency to tell people that their HAs are the same as the name brands. I wonder if they’re trained by corporate to say those untrue things. Even the KS10 is not exactly the same as the Phonak Paradise, although they may be close. But the core of the HearLink 9030 and the core of the More are not the same at all even though they’re similar on the peripheral features and look and feel and accessories.
