Crap company, 1600 pounds sterling for 2 hearing aids from the Chichester branch. Yes I did have 2 weeks trial but it was not long enough, I never got to grips with the settings and in the end I just got fed up with trying to make the system work so I could hear properly. After one stopped amplifiying and the new lady assistant just cleaned the mic (not the speaker) and said it was ok but it wasnt, I decided Id had enough. Particularly difficult for me was wind noise when outside and background noise in social circumstances. Yes they did ask me back every 6 months but the adjustments did not produce an improvement to my listening. Total waste of money. John Foster
