This is my first serger. I don't know why I waited so long. I have beem sewing 25+ years.
                    The threading was easy to learn. It runs like a charm. I have done many projects with it. I read the manual and also watched a few you tube videos.
                    If you are thinking of purchasing this, it is great start up serger. So far Iove the rolled hemming and overlock stitch.
                    I also found Brother customer service great to work with. Happy sewing.
