This is a great product for our needs. We have a motorhome and travel a lot, especially to Colorado. As cell service isn't the best in the mountains, these 2-way radios worked perfectly. We noticed that the reach was about 2 miles while we were driving...but at the top of the mountains with no interference, it was easily 5 miles. We actually need another set for when our family goes camping, and for the price, we will be purchasing another set just like these.
