I have had about 6 pair of private hearing aids, then decided to try the new Signia bluetooth NHS hearing aids. They are fabulous, connect to my iPhone and iPad so everything is brilliantly clear. After care is superb too, I have had several specialist appointments as I have reversed hearing loss and can only clearly hear about 5 letters in the alphabet, the rest could be anything. This is the best it has ever been for me. I would highly recommend you go for the NHS ones, which are better than any private ones I have ever had. Free batteries, free new tubes as and when required, free everything and only a very short wait for an appointment with Chime who are the contracted company for NHS. As said above you can adjust the hearing aids from your smart phone, it is all set upper you when you receive your hearing aids and explained again and again until they are sure you understand. Aftercare can be done online as they can set them virtually too. So easy. Good luck
