Tried a hearing aid advertised on TV. It did amplify but failed the part where it was supposed to pair with my phone. Called tech support and found that they paired nicely with Google phones but not with Iphone. So I sent it back — they honored their warrenty. Then I went to Costco.
I did pay more $ 1300 for two units, but they tested me and adjusted the devices. At first I had to lower their effectiveness. Easy on the phone app. Next I had to change the frequency response, also easy with the app. I had to lower the high frequency because that was where all the noise was. And my wifes voice was midrange, so I raised that. Now I find I am happy — as a bonus, I can listen to music and cell calls over my hearing aid or switch back to the phone.
Costco did a very good job and they will clean the devices while you shop if you go in regularly. But you have to be a member so there is that.
I have no personal experience with hearing aids. But, for what it’s worth, COSTCO was rated number one prescription retailer by Consumer Reports (5/6 2023).
