Elaine & I used ours the whole time, someone else had one but we never heard from him. I know sometimes the channels are on slightly different freqs, channel 3 on my Cobras is not the same channel 3 on my Audiovox. A few of us had our FRS's at the dragon and they worked well on line of sight, if there was a mountain in between, not so good.For future ref
How did the FMS radios work?
I know i tried to text and phone a couple of times, but was always out of signal range?
FRS= Family Radio Service AKA walkie talkie
