This is difficult to thread and many sites have questions about the tension and threading. My needle constantly breaks when I sew with it. After buying it new, I have not completed a project with it. Further the 1-800 number for Singer was constantly busy when I called. I would recommend another brand.

I have this serger, I bought it at JoAnns in Yuma AZ. It is a royal pain to thread and it seems like I constantly have to adjust the tensions on it. I have a Brother serger and I have it threaded (manually) and operating in seconds. It is so difficult to thread this Singer it takes me and my husband close to an hour before it is operating correctly. AND don't buy it at JoAnns, they don't help you with it.

This serger is poorly made. It is a waste of money. It will make you hate serging. You will have half finished projects and mangled fabric laying all around while you pull your hair out and read and re-read the manual. IT ISN"T YOU AND IT ISN"T SERGING. IT IS THIS MACHINE. DON"T BUY IT. You will want to throw it away in less than a year. Save your money and get a different brand.

Purchased this item from a retail JoAnns' It was 249.99 on sale, came threaded.
I had to play around with the machine more than I used it, read the reviews here and on JoAnns' site and decided there was a better Serger out there.
Bought a Brother from Amazon, JoAnn only sold Singer.

Now, in defense of the Singer serger machine, it has a much heavier material cutter, less oiling and a heavier steel shaft, collar combination, than the Brother.
Also, when the Singer was serging it did an extremely good job of overlocking, better than the Brother, in my opinion.

After I became used to the Singer form of threading it wasn't as bad as most of the reviews made it sound.
