To make it short: I am very happy with the part. In conjunction with a Fritz! Box with DECT base has all kinds of delicacies inclusive, which may no other handset! The integrated Wi-Fi, I can with the part so even listen to Internet radio or music from a USB stick, which I have box connected to the Fritz!. It becomes interesting when you have more than one handset operation. All use the same phone book, which is anchored in the Fritz! Box. You can add or delete a phone to someone who immediately is the change at all other handsets effectively. Missed calls are signaled. If you look at this on a device to which signaling to the other handsets is gone. So saves a lot of unnecessary and unpleasant work. What this device is also very good: the display. In contrast to the other two handsets by Fritz! with color display is the fact that the display is always easy to read (you do not always just push a button in order to be able to then read a text or to recognize the battery status Apropos battery:. He also keeps longer than in models with color display The. device is slightly thicker than the other models, but still much lighter than the equipment of Siemens. Another advantage is the high number of possible entries in the phone book. This is otherwise only achieved by the top models of different manufacturers. The range is good . I live on the 1st floor. Underneath are therefore even the ground floor and basement. Even in the basement and in the garden the phone still works. The acoustics in speakerphone could sometimes be a little better. It holds better then a little more distance from the device, but this is only sometimes, and you can hear it even then, so that you can respond themselves. For this price you get guaranteed no other handset that could hold a candle to this one (Fon M2)! What AVM could improve: if you already have a series of 3 devices, which are similar in their external dimensions, then you should to load all 3 models in the same charger! So one must always leave lying around equal 2 cups. This is annoying and a wasted potential! The technical parameters are great, and in such a small design details is the weak point in the end! Incredible!
