Big disappointment with the sound
When a hearing impaired person buys a phone of this kind, he or she likes the service provided to be effective, and here the sound can be increased, but this does not make it any more understandable, as the sound quality is poor to begin with.
I would have preferred to pay more and get a phone that really met my needs. Once again the seller is enthusiastic about his product, but not reliable. Disappointing.
