What do you know about hearing aids that can be purchased online?

I would be a little sceptical about on-line hearing aides. But I do understand about the money involved in continuing to buy a new one. All you can do is try. She may not hear as well because the digital used now is adjusted for each individual person. And her ear mold won't be fitted to her ear. But you never know till you try it. This has been discussed before and you will get some good suggestions. My husband at one time or another, when his hearing aides have broken before the 3 yrs allowed by our insurance, has tried everything. TV ears, the little transistor radio thing, and a cheap hearing aid. They have all helped him at the time he tried. His hearing is too bad now.
