Bought my hearing aids 7 years ago. Never got on well with them. Too loud or too quiet and did not feel comfortable. In loud company I could hear better without them. On the 6 monthly check ups they were adjusted but still not right. The last year they have been trying to sell me new aids but why spend £2000 for a product that I am not happy with. I decided to go National Health. I was seen within 3 minutes of appointed time at Maidstone Hospitaland 45 minutes later walked out with a pair of hearing aids which I have worn 16 hours a day since. NO CHARGE and free batteries which last 14 days - 4 times as long as amplifon. Worn the aids for 4 weeks before posting this review. A very happy NH 'customer'.
