I do not like having to open the cover to change the stitch length or the cutting width. The controls are inside what makes it more difficult to access them if you need to change anything. It is not made by Bernina, it is made For Bernina. You will get the job done, but if I had to buy one now, I would chose another brand. The Juki MO644D is exactly the same as this one. I really mean they are the same. So it is worth checking if you are trying to buy a new serger. It can save you a lot of money. Stitch Performance I have used it a few times, and sometimes the stitches are a little inconsistent. Especially if you need to sew single layers. They wave very easily and you might have areas where the loops just hang off and other areas where they are just fine but all in the same seam. I always have to adjust the cutting width otherwise there will be even more loops hanging off the edge of the fabric. Ease of Use It is not that hard to thread. Obviously, it is not as easy as the Babylock either. It does not have an easy-threading for the lower looper though. The 800DL is the one that has it. Fabric Handling Make sure you do not use fabric that is excessively thick as it can damage it. Durability I only have it for about 1 year. Let's see how long it will last.
