This is a microphone I used with my MacBook. There are no issues with its operation. I used it for about two years, and the microphone part shows no particular scratches or dirt. There are scratches and dirt on the part that secures the microphone arm. Operation has been confirmed. It's very difficult to tell in the photos, but the internal part of the illuminated button on the microphone seems to be misaligned, making the light look a bit strange, but it doesn't significantly affect its use. It was great because I could switch to mute with one touch, change settings on the microphone side, and connect via USB for clear sound quality. I'm selling it because my home environment has changed, and I no longer have a desk.
