I have a Chatterbox FRSX2. The VOX works but is overrated. There have been reviews that call the range 2 real-world miles... 1/2 at the outside is more like it. But within those limitations, it is a good bike-to-bike system. I haven't used it for rider to pax. If that were going to be the primary use, I'd get something a little further down on the dollar scale. I also run a satellite radio thru it for the speakers and the X2 volume does not control the sat radio so I put a Boostaroo in-line.
