@donkramail, I started a thread to review the Rexton Bicore when I purchased them about 6-7 months ago. Here is the link to that thread:
If you are concerned about this not being the latest technology, be aware that Rexton has released an upgrade, called the Rexton Reach. It was released in Europe in early February and was launched in the U.S. a couple of weeks ago. It is available through private audiology practices, but unfortunately it hasn’t found its way into Costco yet. I’m waiting. Here is a link which I started about the Reach:
If you want to find more reviews on Rexton hearing aids, simply read reviews of the comparable Signia product. The reason that reviews of Rexton hearing aids are so hard to find is because the reviewers know that they are simply a rebadged Signia and see no point in reviewing the same product twice.
