I've had this serger for just over a year now - and it's the fourth serger I've used.

I love it. I've used it for sewing diapers and it happily cuts through far more layers than one should ever make a serger serger.

I've used it for more delicate fabrics and I've never had a problem.

It's relatively easy to thread with a helper lever to thread the lower looper.

It has adjustable stitch length and width, can do a rolled hem, has differential feed. It's easy to change any of these variables.

I paid $300 on eBay from a licensed Juki dealer and I am completely satisfied. Worth every penny of a pretty low price.
