Having bought several copies of the craft for an airsoft team desiring to unify our communication system; it is on advice of a friend that was all well equipped. What has us most is the ability to inter act with two almost simultaneous frequencies, roughly we can listen to the crap of a friendly team while keeping a specific frequency to our group. Regarding the technical powers and capabilities of this device you rely on other comments because this is not my forte. Its very useful charging cradle can boost your device leaving this one "tidy" and not hanging out with 5 m wire ^^ / headset for its part is in good order. What my group regrets (but that's specific to our sport) is that the button to activate the tape and talking is really small. A bare hands there but no worries with our equipment and our gloves in the action fires ca énnerve soon ^^
