I gave them a 2 rating only because I think the colors are beautiful, otherwise I would have given a 1 for performance. First of all it breaks a lot, but it also does not stitch continuously on top. I tried rethreading the machine and the bobbin, nothing changed. I suspected it was thread itself so I removed it and replaced it with thread I was using before and no problems. Needless to say I will not purchase this brand in the future.
