I have a brother and have bought 3 walking feet not realizing i already had one at home I have put them on followed the directions. and still its like it does not work i get mad take it off and in the drawer it goes.. I plan after xmas to take them and my machine to the singer outlet here where I bought the machine from and one of the feet and have them show me I'm waitng because I know they will talk me into a trade up like the last time I took a machine in to be fixed lol
