A:Answer For future readers who find this thread: I just got a Theragun Elite yesterday, and it had this issue. Sounded like a tiny screw rattling around. I returned it and got a new one, which does not have the issue. That tells me that it's not intentional. A device this expensive that is designed to move rapidly shouldn't have loose pieces rattling around inside! If you experience this issue, I recommend returning it for a new one.
