Actually, I am a Panasonic fan. But with this phone I was not happy. Since I have an older system from Panasonic, but no longer works properly, I had been thinking again take an investment of the same brand. The reason was mainly that you can transfer the phonebook from one device to another. Unfortunately, that's when the new equipment is not possible because of the phone's memory is located in the base and not, as its predecessor, in each handset. If you then must prorammieren about 100 names with numbers new that's really very exhausting, especially since the entry mode with case sensitive and Curserrücken Panasonic has always been annoying and still is. In addition, calling the name from the phonebook is somewhat delayed because the handset always must retrieve the numbers from the base. So Panasonic has done with this model clearly no progress. If that phone book is not wichig course receives a phone with a good voice quality, Eco mode and good usability. I had no desire to hours of program and its predecessor KX-TG 6722've ordered, because here still works, copy the phone book !!
