My trusty Ms B that I have had for over 4 decades now once had to go in for major surgery. Seems I sewed on her so much that I had worn her brushes to just nubs. Had to have a whole new motor. Since then she has run just fine. She is in semi retirement now, her younger sis does the grunt work and Miss B gets to help newbies learn to sew. Thank the heavens for competent and understanding repairmen who know and love Berninas and who know how much we love our machines.
