Please note that we cannot ship orders from December 29th to January 6th. I used this microphone only once, but it was too heavy and didn't fit well with my arm, so I'm selling it. Purchased in 2023. I bought it on Amazon, so there is nothing written on the warranty. I couldn't find the instruction manual! USB included. I've only used it once, so there are no noticeable scratches or stains.
