Break in period for One Drop 10 ball bearing

My experience is that they are initially quiet for a few hours then go loud. I give it about an hour and if it’s still loud I use a small drop of lube. It usually stays quiet for a long time after that. The reason I wait a little while after it makes noise is that it often will go quiet again on its own. Some might reprimand me for not cleaning, but I’ve been using this method for a long time without issues. I spend very little time messing with them.
