These are real pro walkie talkies! Only their range is overestimated. 6 Km, this is what we would like to believe, but when one lives in a place with trees slopes and walls ... it inevitably lowered! I tried to post my house, at my gate, my brother went to about 1.1 Km straight ahead on a road. In principle nothing was supposed to block the reception of waves on a road, but there were already a lot of interference.
