The Odin M12 has been one run-away success, with the only exception that once in a while we'll hear a user over-tighten the clutch causing the teeth on the "paddle wheel" to snap off. As a service to our fans, we are now offering this parts-kit at our cost to Odin M12 owners. And remember, a properly adjusted clutch is a happy clutch! Your M12 can easily load a million rounds before the paddle wheel wears out, you just have to make sure the clutch is properly adjusted!
