I bought a pair of these Motorola radios and they worked when I checked them out. When I got them into the mountains of British Columbia they had a range of less than 50 feet. I talked to the paid apologists at Motorola's 800 line. They said if I sent them in maybe I would get a replacement set in 4 to 6 weeks. They also hinted that I was too dumb to use the radios. Take my advice: go another direction.
