My dad is 90, living in assisted living, and couldn't work his iphone anymore.First, logistics. You connect the cell phone to this phone. This does NOT use the old connect to the wall tech. Coverage is completely through the cell phone. This phone can be used as a regular phone - dial numbers like push button phone, with one-button calls to 911 also. I got the model with a speaker phone. We found the handset to have much better quality sound than the speaker. More importantly, you can set it to NOT use the numbers as numbers, but to use them as one-button calls to pre-programmed numbers. The numbers have plastic covers over number papers, and you can replace the number slips with pictures. My dad can't see 1 photos anymore, so we used colored initials - nice and bold. Mine is red C that he can see easily. Also, if you take off the plastic covers altogether, there are raised rough numbers. Dad picked out where he wanted one of his friends, and preferred no cover, but he can feel the number 7 on that button.We disabled the 911 button since dad sometimes fidgets and just pushes buttons randomly. Also, the switch for regular vs one-button calling is on the back and not that easy to do randomly, so dad can't switch back and forth by himself, which is good! We don't want him to be able to dial randomly and wake someone up in the middle of the night.We've been very pleased with this. It's given dad several months of being able to use a phone.
