I use their threads all the time. I have every color they offer too. I use their cotton and polyesters. The polyesters are definitely stronger than the cottons so rarely ever break during quilting. I use them on my Innova with robotics. I wind my own bobbins using the same threads too. Have never had an issue with any of them. I also use both their larger cones for colors I use a lot as well as their smaller spools. All fit my thread stand.
