text: My 97 year-old Dad could not use any phone but this one. His vision does not allow him to see the numbers on the buttons, so my daughter made up a large print chart with names that correspond to the buttons. It was easy to program and set up. It is so easy for him to lift the receiver and press one button to reach me. The only problem is that others, such as the aides at his assisted living facility, do not understand how to use it when it is on one-button program mode. I would have liked the amplified audio to be even louder, but that is mostly a problem because my father won't wear his hearing aids. This really helped solve a big problem for us, and I would buy it again, for sure.
