Juki MO-623 Review

Sewing Machine Reviews Recommendation Level : HIGH

Juki MO-623 is an entry level overlock machine. It is a 1 needle, 2 or 3 thread overlock machine. It comes with built-in rolled hem, so that you don’t have to change the needle plate (thank God). You just need to flip a switch. Like all modern overlock machines, this one also comes with color coded thread paths to make threading easy. Thread tension dial is conveniently located and is easy to use. The seam guide on the machine takes guess work out of the equation. You can create perfect seam allowances, thanks to the seam guide.

The heavy duty knife on Juki MO-623 can cut through light and heavy fabrics equally well. The dial for adjusting lower knife cutting width is easy to use and it ensures consistent stitch quality. The work lights illuminate the work space reasonably well. Stitch length can be adjusted using a dial. The machine has a powerful motor capable of delivering 1500 stitches/min, which keeps it on par with the competition.


Juki MO-623 is not a machine with a lot of bells and whistles. It is an overlock machine and it does exactly that. The motor is very powerful (trust me). The stitch quality is excellent except for thin fabrics. The stitch quality for thin fabrics could have been better, it is good, but you can’t rate it as excellent. It is a small machine, it won’t take up a lot of space. The threading is not complicated, but it is not very easy either. However, there is one YouTube video that explains it very well.


The machine is limited to 2 or 3 threads only. The competitions like Brother 1034D and Singer 14CG754 have 4 thread operation as well, which can work against this machine.


  • Excellent build quality
  • Quality stitches
  • Small machine


  • No 4 thread operation

Is It Worth Buying?

I am really impressed by the quality that Juki MO-623 offers. Apart from the lack of 4 threads, it is a quality overlock machine to consider.
