I bought this machine for my 84yr old Grandfather who has difficulties with seeing and hearing. I tried to find a machine that had all the important controls centralized,which this one did. My Grandfater cant tell the difference between the number 0 or 3 on the machine. So most of the time he thinks he does not have messeages.When he deletes a messeage he ends up turning the machine off because the earase and ON/OFF are the same button. But i cant get that through his 84yr old mind.If this machine was used for a family without elders it would be fantastic. But this is diffiently not one for the elders.
