I have now tested the device over a month and am fully satisfied. I have the radio all day long, the device will use during the day sometimes and suppress it in the evening. In this usage keep the battery pack good two days until they must be loaded. Nevertheless, they come to me in the evening actually getting back to the charging station.
I wear the device at work in mener pocket. So far, it has dust, heat, moisture, etc. participated and still works flawlessly.
The operation is quite simple and the sound quality much better than I have of my CB radio in pleasent memories. The specified range of 10 kilometers reflect probably always on direct distance without vegetation or landscape unevenness. I use the device in a rural, mountainous, wooded area and have so far always can make myself understood well. Distance I tested had a maximum of about 7 kilometers. At that distance I could still communicate well. Moreover, I can communicate with my colleagues in the country strokes, where there is no cell phone reception.
My expectations of the walkie-talkie were met.
