Item came super fast! I ordered it late on the weekend and it was shipped Monday. It arrived the next day! The serger came exactly as described, but the video is for a different serger. So be aware that that’s not the one you’re buying. It also had a lot of different accessories like the extended table and extra feet. The serger is really easy to use. This is my first serger and I was able to thread it and run it within the first hour. It has all the basic functions you need. It is really similar to the 1034D from what I’ve seen. The only difference is the placement of the different settings. The 1034D has all the switches on the left side, and this machine has knobs on the right and the cutting width is in a different area as well. That’s really the only difference I’ve seen so far, and I’ve been using 1034D tutorials to get to know my machine better. I hope this review was helpful! I couldn’t find any other reviews for this machine, but I really like it.

I was pleased with the description of the Brother overclock ps3734 and the price was good too! The item came in less time than expected and I love the way the machine works!
