I love the Side Winder that I bought when it first came out. I take it with me to class and it gets used and used by everyone at class or group. My bobbin winder on my machine quit working so I took it in to have it fixed ...almost $100 later I had a new bobbin winder that filled 7 bobbins then never worked again! For me, the Side Winder was a lifesaver and I will never be without one.
