This is the perfect phone for my 102 year old mother. By programming in only my cell phone number she can reach me at all times by just pushing one button. Both the ringer and the speaker can be made loud enough for her to hear.
This phone is being used by someone who is hearing impaired. It has proven to be a great phone for him. The tone and volume is adjustable, the ring tone works out well, and overall it has been a real blessing.
