BSLLTER Hearing Aids with Self-Fitting

I have been buying several models past several months and writing a review for each model. Soon to be released. This one was sent back

The hearing aids died I tried calling Amazon to get their number but they were no HELP. So I spent 600 dollars for nothing .I only have them for about 3 months. This is a Reflection on you and is going to affect how I do business with YOU!!'

I returned them
