This is an excellent machine. It's fast, fairly quiet and a strong sewer. My sewing experience spans over 40 yrs. and this machine is at the top of my list of favorites. They're getting harder to find and I don't think the newer models really can compare.. If you want a serious serger buy an older model Pfaff or Husqvarna, I have both and will never get rid of them.
I was hesitant to purchase as complex and delicate a device as this serger, but was very pleased to find that it worked just fine. I am very satisfied.
Have ordered the manual printed out so I can learn this machine. Even though I have used a serger for 30 years, this one is different. I haven't made a decent coverstitch yet!
