If you really want to help your audiologist, why not submit 2 reviews?
One when you get your nice new hearing aids perhaps? But the far more powerful message is after some time has passed. People want to know that ‘independents’ will deliver the continuity of service that is missing elsewhere. We will publish the second as an update to the first.
Pictures: if you can upload an image, that does add much more credibility to your review. Others can identify with your comments much more. Your audiologist will be very keen to assist if you find this tricky to do.
