I just bought my Seranade and got to sew on it yesterday. I talked to the sales person where I bought it about the bad review and they said the #l problem is that people do not wind the bobbin properly. I sewed quite a while yesterday and didn't have a single problem. It's still early but, so far I am very happy. Can't wait to take my classes so I try some of the many things it does. I got a great deal on mine. They had been having a sale in March, giving an extra $100 off. I bought mine on April 4, and they had not removed the sale sign. So I asked for the extra $100 off. They were kind enough to give it to me. Very nice people. Always happy when I can save some $.
