I purchased this device for our 88 year old uncle who lives alone in another state. He is in very good health, but over the years his hearing has diminished ... although he won't admit it. He is a very proud and independent person. We call frequently to check on him and there have been times that he is sitting in his chair watching television (volume at the max), oblivious that the phone is ringing. Worried, we send someone over to make sure that he is okay, MUCH to his dismay. This device has easily solved the problem. My husband joked that the amplifier could awaken the dead. It is wonderful! My uncle has not missed one phone call and he absolutely loves it. I highly recommend!
