These phones are to replace the same 3 year old phones. My parents, 90 & 89, have no trouble seeing or using the buttons. Took the chip out of the old cell and into the new no problem. I on the other hand got my new one from the cell company who did not have the same phone. Can not see the screen in daylight and some light rooms and the buttons are a nightmare. If you don't need a camera or flip postage stamp size phone, get this one.
