I have used at least three phones before this Clarity Alto Plus, including a captioned phone, and this, so far, is the best one I've ever had that amplifies and clarifies speech. I like that the volume can be boosted while I'm talking, so that it's just the right volume for the person who has called. The light on the left side lights up when there has been a call, so you don't miss checking your messages. All the lights flash on an incoming call, so it would be good for the visually impaired. I like the large screen, so I can see the numbers clearly. The large buttons make it easy to dial. The battery backup allows it to be used during power outages. So far, this is the best phone I've used in the years that my hearing has worsened. Getting a great value through the factory outlet is an added benefit.
