It works fine on my Brother 1500 both top and bobbin. (1500 means threads per second) I have used it on my older Bernina too. It is really good for piecing when you have lots of seams to meet and join. Poly mono thread is much better then nylon. Nylon is the worst thread ever in my opinion. It stretches too much and will cause all manner of problems.
