Seems to be quite well made, at least 2 out of 3 worked as intended. I'm not sure what happened to it, but if you pull the handle down to shut off the airflow, it still lets air through. It could be an easy fix, or it could just be a bad ball valve. I'll know more when I disassemble the airline so I can report why a valve failed.
