After two weeks of use, I am very satisfied with the Panasonic devices. The understanding is clear to read the screen very well with the large font. The phone book is automatically when filling in all registered handsets; An entry is deleted, for example, this is done at the same time with the other devices. The keys have precise pressure points, the handsets are pleasantly light and fit comfortably in your hand. A further advantage is the "Eco" key with which the current consumption can be reduced to a minimum. The handsets are spread over three floors with us, without resulting in Eco mode in communicating to impairments. If one considers, for example, in the open and thus further away from the base station, you can significantly improve the possibly poor voice quality by switching off the Eco function. The only drawback for me is the lack of the mute button (crossed out bell), which, however, according to Manual (page 20) to enter! But it is definitely not available. So you have to, you want to temporarily turn off the ringing of a handset, this awkward on the "Settings" menu, "Ringer Volume" do and then turn on the sound in the same way again. Therefore only 4 stars. I can not say anything because we do not use it on the answering machine. Buying this phone sets I highly recommend despite cumbersome mute function.
