I bought hearing aids in November 2018. I have had to return 7 times. They will not give my money back. They said this last time that there was nothing wrong with them but I suspect they gave me new ones. A complete waste of over £2,300 and that was with 50% off for a "returning customer" and because I bought 2!!! Save your pennies and get National Health hearing aids - at least you get a decent service. They are not fit for purpose. I had Phonak hearing aids for 6 years with no problem. The only reason I had to replace them is because I lost one. Boots had taken over my hearing aid provider. The new ones are hopeless. I am articulate and compus mentes. God help those who get conned into buying these and get no use out of them simply because they cannot return them and explain that they DO NOT WORK for more than a few weeks.
