  • Excellent Overlock Machine
I had read excellent reviews on this machine and decided to purchase one, I’m a Bernina owner and called my dealer to buy one. However, they didn’t have any in stock and couldn’t say when any were expected. I googled where I could buy one online and was surprised that I could buy one from Amazon. It delivered within days and at a better price than from my sewing machine dealer. It’s a great machine, very easy to use. The Airlock threading system is absolutely wonderful. ... show more

  • Fabulous
Great stitching and easy to thread. Only wish it brought the manual with it.

  • finally an easy to use overlock
I've had one other overlock machine and gave up on it as too difficult to be useful. So, I consider myself a newby to overlock and coverstitch machines. A 5 thread combo machine is intimidating at first sight, but it is so easy there is almot no learning curve. I did watch the Bernette videos. The air thread lopers are amazing. And I love the knee lever control for the pressure foot. ... show more

  • Great machine
I love it….but couldn’t get Bernia warranty because seller wasn’t a dealer. Broke my heart to return but expensive enough not to take a risk. Also bought the 3 year warranty but that only paid what the Bernia warranty didn’t pay. SO…..NO WARRANTY

  • The best features for a price that won't break the budget.
I have always had Bernina's when I was working. Bernette is not quite the quality of Bernina's. But most of us can't afford the price difference. The air threading is such a blessing for us with "mature" eyes. I got this at a super introductory price, I couldn't resist. It is well built, heavy. It is somewhat noisy as to my last Bernina Serger/coverstich, so I had a wool pressing matt I wasn't using and placed it underneath. Much better. Threading and changing stitching styles is easy with lots of YouTube training available. ... show more

  • Problem with threader
Air threading didn’t work on upper looper. Lower looper threading worked fine. Disappointed I had to return this machine and was not able to get a replacement. It’s a nice sturdy machine, love the lighting, extension table, free arm, and right side presser foot lever. I’ll keep shopping.
