A quick search on google or Bing shows me that there are very many companies advertising their services to service hearing aids. It seems that the range in cost for a hearing aid repair is between $30 to $100 and these generally come with a 6 to 12 month warranty. The providers also offer full hearing aid rebuild but the prices are generally higher, more in the range of $175. On the surface I have to suggest that this is sounds like a great deal. To fix a $3000 product for as low as $175 is a fantastic deal.
