This is the 4th part of my wishlist to audiologists and accousticians, hearing aid manufacturers, and the health care system. If you like to add something, share your experiences, or provide more information, I encourage you to submit a comment.
Audiologists and accousticians have opening hours which are not compatible with a schedule of a working person . They usually open only between Monday and Friday 9 a.m. and 6 p.m. and most of them are closed on Saturday, with the exception of a very few shops in very big cities. This makes it nearly impossible for me to see an audiologist without spending valuable vacation days or risking trouble with my employer.
This is especially bad, when my hearing aids break. If they break on a Friday night, I have to wait until Monday morning to see my audiologist. Most likely, he will not be able to repair it right away, but will give me a spare hearing aid, which will mostly not be of the same model as my own hearing aid. Since the settings are not compatible between different hearing aid models, those will be poorly tuned and cause me a lot of distress.
What I want is a service similar to what you can buy for your car or your computer. If my car breaks down somewhere (not even necessarily in my home country), I can call that service and they come to me, repair my car right away or bring my car to the nearest repair shop and transfer me to wherever I was going. There is no service like that for hearing aids, although I am much more dependent on my hearing aids than on my car. I would even pay for it, but so far I have not heart of any offers like that .
I would even be willing to give my audiological data and hearing aid setting parameters to a third party provider if in case my hearing aids are broken, they guarantee to provide me with a set of hearing aids of the same model as I usually wear tuned with my parameters within 24 hours. It would be great if that was not only available in my home country, but everywhere in the world.
 This might only apply to Germany, I cannot give an exhausting description for other markets. Feel free to add comments about that.
 I heart rumors that some vendors offer service like that, but only for some of their hearing aid models. And so far, I haven’t seen those offers.
