So far I have operated two Fritz boxes (currently the 7590), and both have worked or are working. In addition, telephone, repeater and sockets. Everything okay. I haven't had to use the service yet. The device setup works well. Even I got along with it. It would be nice to have a slightly larger battery for the phones. I don't find the color white so sparkling either. Note: I hope that AVM thinks about customer service. After reading through the reviews, there seems to be a lot of room for improvement.
