Just bought a set of HD helmets with 30K and only works about 50% of the time. I find anytime I get around power lines it gets really garbled like a bad cell phone call. Distance doesn't seem to make a difference. Only thing that improves it is restarting the mesh comms, but that only lasts a few min. When I use my phone GPS it drops both volumes so low I can't hear either one. Really disappointing considering the price!!
