I use my Brother adapter on my (old) Bernette which was given to me by my sister but she had somehow lost the adapter part. This works just fine. ONLY: the Bernette snap-on feet are just a little different size so those can't be used now as the needle will hit the plate and break. Brother and all mygeneric feet(I've collected about 30) are fine so I can use those in both machines with Brother adapter. So try first turning the wheel by hand SLOWLY to make sure before using the original feet with other adapters.
