Purchased in 2022 and used with a PC. It seems to be a broken wire, as input sometimes gets stuck or the connection is lost. Manufacturer support has ended, and I am unable to repair it myself, so I am selling it. Please purchase only if you can use it for parts or repair. I wiped it down, but it has been used for a long time, so please refrain from purchasing if you are concerned about stains such as handprints. No returns or claims accepted.
