I bought this thread to use with my Brother 2504D, and also for free-motion embroidery on my regular machine. I didn’t really have high expectations at this budget price, but am actually very impressed with the performance. I have just used it for free-motion quilting on a small wall quilt. This is really hard on thread, as it has to pierce pieced top, batting, and backing, and the speed does not have the smooth acceleration and speed of a computer-controlled embroidery system. I also just used the needle already in my machine - a universal 80, I think but certainly not an embroidery needle. I completed the entire project without a single break, or fraying, or stitch skipping. Comparing the appearance of the thread and the finished result to some expensive thread, I don’t see any difference in the results. I will certainly be buying this brand again.
