@GPz. I don't know if you are a hearing aid user, but if you are you will know the business is an intricate nightmare. It seems that brands and retailers are constantly being bought and sold in an effort to concentrate the market, probably to the detriment of the consumer. If you pay full retail these things are stupidly expensive.
In my case I used House of Hearing, which after I stopped using them, was taken over by Bloom, hence my name is on the list.
