I purchased this thread in many different colors at my local fabric store. I was surprised that the price at my local store was better than what I could find on line (both 3,000) yards. I am new to serging but was told by the sales clerk that this was a good serger thread (they did not have many other options so I am not sure that she would have said if it was bad). I have noticed that the thread is not perfect but is fairly smooth. I have sewed a number of little projects lately and only broke one of four threads once. I think the break was largely a user error and not a thread quality issue. I first bought four spools and liked it so much that I went back and bought 8 more spools.
