My Mom got hers a few years back, do your homework ahead of time.. What type of hearing loss is it.. as the different types work on different causes. Be prepared to go back for adjustments till they get the setting right. At first my Mom's was set so loud that just closing a cabinet was like a door slamming. She still can not hear certain voices ( there is a range or certain frequencies that no aid will enhance). Get the range of loss diagnosed before your shop for a hearing aid. Make sure the cleanings and follow up adjustments are included. Ask for a satisfaction gaurentee. It 's a lot to spend and if she is not happy with the first one ... its often the reason they settle for less as the cost of trying another is prohibitive.
