The tests were very thorough. Some I had never had done at previous locations. Hearing aids are very expensive for the patients.

Went in to get the first follow-up. Sue again was great. Cleaned the hearing aids and tweaked the settings for a couple of the programs. Reminded me of the edge adjustment. Already used it. Great set of hearing aids and the audible staff are wonderful.
