It' good and I did buy several sets a couple of years ago...the only thing is it is very very linty and my Longarm will stitch well with it, but I have to continuously clean out my bobbin area and the disks on the tension knob....I also use it in my regular Janome 6600, but like I said, it is really linty....I want to try their poly thread, just wish they had more of a selection....
