This is my first serger. It was not very easy to learn how to use. After hours and hours of practice, I finally taught myself how to use this machine. I does not typically take me that long to learn ANYTHING, especially when it comes with directions. After learning the machine and the processes that one must take to first thread this machine (holy smokes,) it is very easy to use. It makes excellent stitches and I love using this machine for a good finished look when I make clothes for my kids. Stitch Performance This Singer serger had good strong and tight stitches. I have not had any problems with missed stitches. The stitches are uniform- and all my sewing products have a good finished tough when I use this serger on them. Ease of Use This is really easy to use, after HOURS of reading instructions and trying to figure out how to thread this machine. Once you figure it out, it is a breeze. Fabric Handling This serger handles fabric as expected. I have not thrown anything crazy at my machine yet. It handles the basics (cotton, jersey, knit) quite well. Versatility I feel that I could do a lot with my machine. I have not tried to do too much with it, just basic finishing on clothes. Design I love the way this machine looks. It looks industrial to me. When it is on my sewing table, I feel like a professional seamstress!! Durability This machine is really strong. I probably should have broke it several times when I was trying to learn how to use it, but it still works like a champ.
