Purchased brand new from copper.The mic sounds great real good punchy audio.Now heres the bad.The tx light wasnt working i found the wire clipped on the inside.I was able to touch and tape them.The other thing its very easy to overdrive my radio hums with modulation past 5 on the slider.I have my radios mic gain at 11 "half" modulation on mic is five and echo 3.Another thing i wasnt to fond of is the ptt button is flimsy and catches easy.For the price i paid the audio is worth it but the build quality is sub par.
