Had NHS hearing aids from Scrivens but the audiologist gave me little information---told me to clean hearing aids every 2 weeks which is nonsense. I was not given enough time to master inserting then myself. I did not received the promised telephone call after a week nor the follow up appointment 3 months later. I only received a telephone call from a very pleasant girl who answered several of my questions. Currently I am trying to obtain new tubing as I have lost the dome but despite 2 phone calls and 2 emails have heard nothing. Very disappointing experience
