Yes, I appreciate your point, z10user2. And I am very grateful for your understanding of how painful my present situation feels, if I cannot get some improvement to possibly get me back to how great my KS5s worked for me up until the past year or so, either by adjusting or replacing them.
By way of additional background pertinent to your suggestion of other and/or more expensive providers, I would add that I have had the KS5s since 2013 and until the past year or so, the Costco Hearing Aid center and the KS5s have provided me with what I have felt has been an experience far superior to six years before 2013 when I had spent $7000 plus on then “top-of-the-line” Phonak Audeos and accessories purchased from a well-regarded local audiologist, whom I also paid about $300 yearly beyond the first two years for servicing notwithstanding the fact that those visits consisted mainly of him demonstrating how loudly he thought she should amp up her voice every time she spoke to me. (If everyone shouted as loudly as he would demonstrate in a megaphone-like voice, none of us would need to bother with hearing aids at all.)
For those reasons I feel more confident sticking with the Costco Hearing Center at this time, although I appreciate the fact that others may have had a better experience elsewhere
Best wishes, Nate
