Received "Brother SA107 Walking Foot"; it was not made by Brother but a cheap knock-off (ahf-1011-5ls/wo) which I think was poorly made. It did not work for even half of the first quilt it was used for. Cost to return would be more than it’s worth, trash canned it. Bought real Brother brand name that works beautifully and is much smoother and quieter. This is piece of junk; do not waste your money on it. C.T.Williams
