I sent for this kneading blade with some tredipation wondering whether it would work, as it is for multi-types of Panasonic breadmakers. Goodness knows how I lost the original one but I was thrilled to find that this new one looks the same as the original and works just as good. It was good value for money, too as some websites only sold it as part of a set some of which were quite exepensive, and if you only need the kneading blade would have been a waste of money, so altogethr I was very pleased to be able to make my loaves again at a reasonable price. Incidentally mine is the SD257. It came quite quickly too.
