The radio works perfectly, and the daughter device HS40 can be coupled without any problems - the display could be a bit larger, especially for the AIS display. Almost all functions can be displayed via the daughter device. Battery capacity is sufficient for one day's use after a full charge - without using the charging station too by induction.
Due to the installation situation for the radio, I need this handset. The functionality is good, the display shows all important data and functions. The audio quality is also good. I can't say anything about the range, it's just WiFi. The size and shape of the device are negative. It is very large and clunky. The setting for the internal external speaker changes every time you start it. The battery life is sufficient at 5-6 hours. Theoretically, the functionality could also be taken over by a mobile phone app.
