It will work in the following BERNINA machines:

B700 E, B 735, B 740, B 770 QE, B 790, B 790 PLUS
B 500 E, B 535, B 570 QE, B 590

TIPS:

Basing on the higher bobbin thread tension due to the bobbin case, adjust the upper thread tension about 0.5 to 1 higher compared to using the standard bobbin case. Refer to the instruction manual of the machine.

If the bobbin thread is visible on the right side of the fabric, reduce the upper thread tension.
If the upper thread is pulled to the wrong side of the fabric too strongly, increase the upper thread tension.
