I've got a high frequency loss in both ears. Bought a pair of high dollar aids some years ago that worked well, but after the warranty period one or the other would need something done every year or so. Always cost $200 or more to get them fixed, so I now wear a pair of Walker Pro Elites @ $150 each. Had them for 2 years now with no problems and they work as well as the $3500 set I used to use.
HTH, TomJ.
