I almost always use my bobbin winder. I laughed at my husband when he suggested what a useful gadget it would be.
however I finally bought one Im one of those people who really investigates purchases of gadgets they usually wind up collecting dust. however this one paid off I no longer have to stop it seems like every 5 min to make a bobbin I also keep bobbins made up ahead of bobbins I use all the time like white black and off white. I even depend on the one at my mil sewing house too hardly anyone touches it but me lol. and yet again I get the honor of saying yes honey you were right lol.
