Display large letters, as have its predecessors already described, very narrow, but with full eyesight not an issue. Is also in my view irrelevant, after all, I want to call it and not read eBook.
The operation is very easy, the initial connection you get back even with a minimal understanding of technology and without guidance.
What struck me today and why I directly 2 stars depart: I was on the phone with me and in the background the church clock began beating. My interlocutor was just the telling. Every time the clock struck, the other party's voice FULLY was suppressed. That is, it has been told something, but you could not hear anything more with each stroke. (I guess to avoid feedback or something.) That's a No ... So call only with the window closed. ;-)
Otherwise very satisfied.
