The Towa allows you find a number associated with 'perfect tension' on your particular machine. Once you have it, you can easily and quickly adjust every single new bobbin to that same number, pop it in and go. Easy peasy :) No playing around or wondering if the tension is the issue or playing righty-tighty, lefty-loosey games. Just pull the thread, read the number, turn the screw to adjust to your correct number, and pop it in and quilt. Perfect everytime, regardless of thread, thread weight, thread content, fabric, etc.
I love mine.
