I am glad my journey was helpful. I don't know if you saw my later post where I lost my external processor at the vets office and was able to track where I lost it to no avail. After searching for a couple of weeks and returning several times to see if anyone turned it in, I gave in and had to get a refurbished one. It is okay, but does not seem to be as good as my other one. Just be careful with the tether. The tether clips do not last long and break easily which is why I lost mine. Other than that, I am still amazed at the difference it has made...not perfect, but much better than not hearing anything at all.
