I’ve been sewing for years but just recently stepped into the world of sergers, and the Juki MO-50E has made that transition surprisingly smooth. This machine is a great balance between power, precision, and price especially for home sewists who want to elevate their garment finishes. 🧵 Setup & Threading Threading a serger can be intimidating, but Juki has done a great job making the process less painful. The color-coded threading guides are clear and accurate, and with a bit of patience, I was up and running in under an hour. Bonus: the automatic lower looper threader is a time saver once you get the hang of it. ✂️ Performance The MO-50E runs quietly and smoothly, even at high speeds. It handles light to medium-weight fabrics with ease from cotton knits to linen and lightweight denim. The stitches are even and professional-looking, and the built-in rolled hem function is fantastic for finishing edges cleanly without switching machines. ⚙️ Adjustability & Features I appreciate the easy-to-adjust tension dials, differential feed, and the option to switch between 3- and 4-thread modes. The knife cuts cleanly and consistently. For the price, you're getting a solid feature set. If you're looking for a reliable, easy-to-learn serger that delivers high-quality results without jumping into industrial territory, then this is the machine for you. I’d recommend it for confident beginners or anyone upgrading from an entry-level model.

I would like to start by saying that I am not being paid to write this review, nor did anyone solicit me to do so (other than the normal Amazon request). I am writing it because I appreciate hearing from other purchasers and want to pay it forward. I want to also say that this is my first serger. I have been sewing my whole life...my mother was a seamstress. She never had a serger, so I didn't think I needed one. But she didn't really sew knits...I find myself using them all the time. And, while my sewing machine has a knit stitch, I'm finding the serger SO much better!. This little machine works really well and didn't break the bank. As to some of the other comments, it does come with accessories! They are in the accessory drawer on the left side. If you can't find them, read your users manual. Also, it is not hard to thread. Yes, it is a little complicated, but watch the video and (again) read the users manual. Just like with a sewing machine, there are several steps -- for one needle and the bobbin. And, with 2 needles and 2 loopers (works like a bobbin but without the spool), there are several steps times 2. But none of them are really hard...just go slow and you'll get it. You can also tie your thread to the thread the machine came with. Then, don't try to pull the thread through, just start sewing. It will thread through perfectly. You will, of course, have to thread the needle itself, but that should go without saying. Overall, I'm very happy with my purchase. Time will tell if it is well built -- seems to be -- and if it will work on all types of fabric. I've tried a few and so far so good!

As someone with a lifelong passion for sewing but never felt the need for a serger, this machine has been a game-changer. Coming from a family of seamstresses, I was skeptical at first. However, the convenience of working with knits has won me over. While my sewing machine offers a knit stitch, the serger's performance surpasses it by far. Affordable and efficient, this little gem has truly impressed me. Highly recommend for anyone who loves working with knit fabrics.

I bought a Juki 4 thread serger machine on line from Amazon which was my first purchasing there. I’m satisfying this machine meanwhile Amazon for good services. It has guiding book + training disc. I had time to return if I was not satisfied. Thanks Amazon for good services to customers.

This maching is very good and I'm still learning how to use it. I love that there are also available videos to look at for its use

I've been sewing for 50+ years. I have a Juki industrial sewing machine that I ADORE, so I figured this serger would be just as simple to use. I HAD a serger that I used until it simply fell apart. That serger took me 5 minutes tops to thread. This one? I just wasted 2 hours trying to thread this one. I figured operator error, but then nope. That lower looper horked up every time. First the latches and catches are extremely hard to put the threads through. The tension was really tight, even after I put everything on 0. The lower looper with the "auto threader' is an easy to miss, impossible to thread portion, and that's the one that matters. It would not catch. I tried so many times. The portion that holds the knife doesn't move out of the way, so you get to attempt to thread the needles around the knife. I'd rather be sewing, not wasting my time threading my serger. Enough is enough. I'm getting the air-threader serger. More money, way less stress on me.
