Fully satisfied! Finally direct access to the phone book and answering machine of Fritzbox! Had previously registered Gigaset, because it was really awkward to get to the phonebook - 3 clicks! Also listen to your mailbox! Have only ordered one because many reviews were not good here! Forced delivery 1day! Unwrapped, battery pure DECT button on the Fritz box and you're done! Information about a new update came after 2 minutes. Pressed on "Install" and then it started up again! Finished! Indispensable for Fritzbox users! Phone is self-explanatory! Top Design! Have equal a 2.bestellt! Super Easy! This could even my hamster ;-) Sound is great, noise is not present with me, connecting with ISDN!
