We have now used the radios for the first time on a long drive with 2 minibuses for a fan club trip. The range is located on the highway at about 1km. Further away there are disturbances and only fragments are to be understood. But since we are almost always behind the other dangers in sight, all was well. We have the equipment for short-denying of whether to stop at the next rest stop, or planned maintenance fails, used. The voice quality was good. Sometimes you had to repeat the spoken word. One must note only that one does not immediately release speaks after keystroke, but a little while waiting. Otherwise, the first word is not. We have also grown accustomed even to push forward to the button briefly before speaking. This makes it beeps briefly at the other and you will not be surprised by the radiogram. Overall, the devices have paid and are determined more frequently used.
