All the sewers who say they only use Bernina bobbins are doing it
the right way ,My son is our local "Bernina Man " and has been for 26 years
and when I got y first Bernina machine he said his only rule to me was
"Mom only use Berninas bobbins and needles " and you wont have problems
with your machine , and he is right I have had my 830 for 4 years now and
it has been into the shop twice...when it comes p or its service .Think about it would
you put Ford parts into you BMW car you have paid good money for , to me my machine are
worth a much. Cathy
