"Awesome machine. My 3rd serger. I waited to review just so I'd have some time with this machine. In short: it's great. I spoke with a knowledgeable Juki Rep and he told me the motor is the same as one of their higher end models. I recommend this MO-114D over the MO-104D. the 114 is cheaper AND comes with the upper looper converter for various additional stitches which the 104D can't make. Also the 114D has the differential feed dial on the outside of the machine so I can adjust while serging. The 104D has the dial INSIDE so you'd have to stop serging, open the machine to tune the differential feed, close up and begin again. (dunno why the 104D is $50 more for less functions). Arrived on time and in great condition.
The manual is good but leaves out some details which I figured out through trial and error. The machine does not move or rattle around my table at high speed and is surprisingly reliable. No complaints. Easy to thread"
