Rated 1 out of 5 by from Not worth the money I haven’t had my machine a good six months. I bought in in June of this year and It stopped working 3 months after. Took it to a specialist and they told me that my warranty didn’t cover what was wrong with it. They said it needed to be cleaned out. I had it cleaned out and it still doesn’t work.

Rated 5 out of 5 by from Great Machine! I bought this machine to use on quilting and it worked awesome!! At first had a little trouble with threading but watched the video and took advice of rethreading the whole thing and it did the job!! Would advise anyone to get this machine! I love it!!

Rated 5 out of 5 by from great machine I bought this serger after my old one finally wore out after over 20 years of heavy use. I didn't think I could replace it and expected a lesser product. I couldn't be happier. The new one is as well made,in fact it's better!. Looking forward to getting 20 plus years out of this one.
