    Wonderful product Adult Homecare Facilit

    My husband started losing his hearing before he went into an ADULT GROUP HOME and got this product ... It saved my hearing . Then he went into a GROUP HOME and in his own room with a TV ..... It was wonderful because he was no longer able to walk, see or hear as well. When someone walked into the room to talk to me, I would put the TV remote on mute and he was still able to hear the TV program. I missed having one for myself now that I live alone, so I got one too. It's a wonderful to use it while doing other things around the house OR even gardening. If I leave the room I never miss the ending of movies or programs. If I lay down I place it by me on louder volume . Best to BUY 2 of this product :)

    My wife likes it better than I do - she doesn't have to tell me what someone on the screen just said anymore.


    Works as advertised
