I bought these hearing aids a few months ago with great hesitation because of their price. My mother is 90 years old with a severe hearing problem. Years ago she had bought expensive hearing aids in the range of 2,000 euros, which, apart from needing regular battery replacement, wax filters, and ear tips, and having a high monthly cost as well, did not amplify the sound satisfactorily. We got these to try after 3 others of different brands and prices. I turned them on to see how they sounded and was left speechless. Good sound amplification and no feedback. I gave them to my mother and at last she can hear me without many adjustments. They easily last at least a whole day on one charge. I ordered and received another one today. The price-to-performance ratio is EXCELLENT.

It does the job just fine. Of course, don't expect HiFi sound but it is more effective than more expensive solutions I have tried

Although I didn't believe it would work, my father heard much better than with the very expensive hearing aid he had. There is a bit of difficulty if someone wears prescription glasses. However, you get used to it.
