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.

3. absolution, remission. Pardon, amnesty, reprieve are nouns referring to the cancellation, or delay with the possibility of eventual cancellation, of a punishment or penalty assigned for the violation of a military regulation or a civil law; absolution from guilt is not implied, merely a remission of the penalty.
