What can I say: I have now had the device for the first time in use, and at first everything worked wonderfully. We use it in the sound equipment for sound check; because communication is much more pleasant than the same as if you have to shout over the place. Call quality is top and can not be compared with the walkie talkies from the 90s. The distance test, I have not done, but what I've heard, I already completely convinced. This unit can not go wrong. The parts are worth the money anyway.
