The battery charge symbol never changes so you can't tell how much charge is in the battery, which caused me and my friends in a bit of trouble one day when they ran out of charge on the mountain and the radios stopped working.Also there is no PTT microphone accessory available for this radio. Uniden only produces the voice operated headsets, which I think is ridiculous. I wanted to use these radios while snowboarding and there is no way I am wearing a headset on the hill let alone a voice operated one, on a windy day i'd be transmitting wind gusts all day to my friends as well as looking like a knob.
