The NHS hearing aid used by Scrivens are not fit for purpose. As they constantly have white noise, and you hear background noise above the conversation you are trying to listen to. Also you are not trusted to operate the volume level you need, as it is fixed at a level by the technician who does not think at I am capable of using it sensibly. So I don not think the service is even good enough for the one star you are forced to rate it with.
