stitches won't lock on Singer

Lately I have found that many of the new metal bobbins both for my 401 and my 15-91 DO NOT FIT or operate properly in the machine. Only the old ones work. Lots of the new ones especially the 401 bobbins just build up birdnests, and I do know which way to insert the bobbin, the 15 91 bobbins are so poorly machined you can see the little slot is not straight, and that little slot is what makes it fit downon the bobbin winder post.:)

The ladys at my Brother shop told me that the metal bobbins can become magnitized as you sew fast.She said to only use the plastic ones to stop that. After changing to the plastic bobbins I dont have that problem any more.
