Pls see above reply to this issue.
It’s a combination. If the bearing is in place before tightening the yoyo it won’t be a problem. If the bearing is placed loosely in the gap and the tightening is used to seat it the seat got damaged. As mentioned we made changes to reduce the possibility of this occurring but it’s still a good practice to make sure the bearing us located before tightening on any brand of yoyo
