Hello, I just bought these phones since 3 days (07/08/13) I can already tell you that I find very easy to program combined reading on screens and not very good magnifying glass need to see . The keys are well designed large digits and well spaced so as not to press both at the same temps.40 melody choices for ringing combined some are discreet, others funny then you are obliged to find one that suits you. Can adjust the ringer volume as well as that of the answering machine too, with me personally it's pretty great I put the phone volume and answering maximum I guarantee you that it sounds very strong (remains to be seen choosing melody) Combined with a very good light on the bases, the TAD displays digital numbers by the number of messages received in handy as a blow Flirted you know if there have been message or not. A large directory with search capability of people use the first letter, good sound reading .... many other options possible. I think you would not be disappointed if you made the choice of this purchase I had as many gents changing the phone several times and there I am already satisfied in 3 days of use, remains just a hope that they will last in time. Regards Sandrine
