MO-50E, 3 or 4 Thread Serger, Lay In Tensions, Adjustable Differential Feed, Built In Rolled Hem, Automatic Lower Looper Threader, Retractable Upper Knife (MO-50E/UL)

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!

No problems with it. This was my first serger and the learning curve on threading is high! The first time I had to re-thread the whole thing (color change) it took me approximately 5 hours over the course of 3 days. I still dread if a certain thread ends up pulling out or breaking. Word of caution, have tweezers on hand before you start! It will help. Tensions were fairly easy to set after reading the manual. Keep the manual around to refer back to it. I have used this for many projects. It is a must of you want to sew with knits or make apparel.

I bought this serger to replace my Brother 1034D, which broke irreparably after just a few months of use. So far, this one feels much sturdier and more capable. It handles multiple layers of thicker fabric like a champ and simply glides through them. My Brother had fits going over thicker seams, so this is a huge improvement. Plus, this machine has a nice, clean stitch. I also appreciate the seam allowance measurements marked on the front casing. However, this machine is a lot more difficult to thread than the Brother. It took me several tries (including watching the instructional DVD multiple times) to get it threaded correctly the first time, and even longer to get the tension right. I've since had issues with the loopers becoming unthreaded in the middle of use—even when the machine had been working correctly for a long time. And when that happens, there's basically no chance of just rethreading the problem area. You will have to rethread the entire thing from scratch in order to make it work correctly again. It can cause a lot of frustration when this happens in the middle of a seam! Overall, I'm pleased with the purchase, and I think it's a great value. The finicky threading may scare away beginners or those looking for an easier setup, but for those that can look past that, the Juki MO-50E is a solid, powerful machine that does a great job.

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 intended to use the machine a little longer before writting the review but I'm just so excited about this machine I couldn't wait. I have been sewing for about 40 years. I grew up when sewing wasn't a craft, it was a matter of economics so we had to learn. And we always used a Singer. When I bought my first serger, it was a Singer Stylist. It has always been a struggle to make it work correctly - I spent more time coaxing it into working than I spent actually sewing. When it died a sudden death, after only a couple of years, I decided to try this Juki. I LOVE IT. It threads quickly and easily and sews a beautiful seam. MY old Stylist was loud and vibrated a lot; this machine is much quieter and runs very smoothly. My old Stylist machine was tricky to thread; this machine threads very easily, I got it right the first time. (Playing with the new toy: I unthreaded it many times just so that I could rethread it and make sure I could consistantly thread it properly.) I have already sewn a few garments and can tell this machine is a real workhorse. I hope to buy an electronic sewing machine soon and it will be a Juki. I have given up on Singer (many reasons why, but this is not the place), seems the old reliable ain't so reliable anymore.

It works great for a regular 4 thread serge, still having problems figuring out a rolled hem serge. Also, has a strange smell, like electrical, whenever we use it. I called and they said it was normal and that it should stop after a few uses.

The Juki MO-50E is a fantastic 3/4-thread serger! The adjustable differential feed and built-in rolled hem make it versatile, while the automatic looper threader saves time. Smooth, precise, and easy to use—highly recommended for both beginners and pros!
