I bought 2 easy winders on Amazon several years ago. I love Love mine! but the nieghbor I gave the other to never uses hers. I taped mine to the shelf next to the machine and put old bobbins on the extra bobbin holder pins. an extra wrap when threading took care of the tension problem. I am now using a kenmore from sears. it also worked with a brother and a white. It's kind of hard to get the kenmore bobbin on. very tight! but it works!
