I recently tried out some hearPod aides.
I started out with the canal type aid and then sent those back and tried the behind the ear open fit style.
I felt that the open fit was much better for me, but after some consideration, decided that they weren't what I was looking for.
I have a somewhat non-typical loss.
The point I wanted to make was that HearPod was very easy to work with and I had no problem at all in getting a refund of my money.
In all I paid very little for the chance to try two of their aides.
