I have had the unfortunate luck of being gifted a bad singer sewing machine. This Christmas I was bought a brand new singer quantum stylist 9960. It was a beautiful piece of machinery, and when I looked up how much it cost I was expecting it to work as well as it looked. Unfortunately that wasn't the case, I have not been able to finish a project without having some form of difficulty from the machine and no matter what I do, it will not run as well as I had hoped. There appears to be a problem with the bobbin casing seeing that the bobbin starts to build up multiple threads at the same time, I have tried turning the bobbin different ways, but it always does the same and it pulls all of my projects into the machine, a few so far that it tears the projects. It's unfortunate because it really is a beautiful machine but I wish it worked like it should.
