I can't understand how most of these reviews were negative. My wife is functionally quadriplegic and blind, but speaks well and uses the phone easily. It works exactly as stated, and usually on the first try. It is critical that you state names and commands consistently and with the same inflections, with no background noise. Within half hour I threw away the original packing and cancelled her emergency pendant service. It's a keeper.
