We gave these radios a test shortly after receiving them. Took one for a hike and left another at home. The trail-head for my hike was 16 miles from home and I had a clear crisp signal at the start. While on the hike I added a few more miles to that distance and was still able to communicate without any problems, even while in heavy timber. It wasn't until I started rounding the back of the mountain and lost line of site that the signal was lost, just like all walkie talkies do. We are quiet please with how these radios have been holding up, our Scouts have used them several times and are no worse for wear. Great to use with out Scout group as we can stay in better communication during our activities and trips, especially in those areas with out cell phone signal, which is the location of most of our activities.
A very good quality 2 way radio at a low cost. We have another set of Midland Radios that these work just as well with.
