Excellent beyond all expectations. There is some difficulty with the settings. Maybe I am not handling it that well myself.
Anyway, if there was a tenth star, I would give it.
It is more than worth it.

It looks quite high quality, the settings from the mobile are decent, however, the fit regarding the shape of the ear is not the best in two aspects:
a. the length of the cable from the external part to the part that goes into the ear canal (it is relatively short, my mother, although she has a relatively small ear, because the canal is quite low, the cable does not reach and it makes placement & stability of the external part difficult).
b. size and shape of the part that goes into the canal. Again, because my mother's canal has a slightly unusual shape and position, it does not go in deep enough (regardless of which silicone tip we use), resulting in feedback and we have to keep the volume relatively low, so it does not help her as much as it could/should.

One last thing. It's not a problem but it's annoying and I don't know how to describe it regarding the manufacturer:
To get the app to work on the phone, you have to turn on the GPS. Seriously!!! How much stupidity from the manufacturers? Why does the hearing aid need to know your location?
They've gone overboard with the nonsense in the apps, soon they'll put GPS in cabbages too!

She has already had it for 10 days, and for the reasons I described above, she hasn't gotten used to it much.
