Never heard of it before, but I did watch the video and checked out their catalog. While the idea of the thread coming off the spool does make sense, I don't recall having my metalic thread break as much or come out as messy as he demonstrated.
Guess I'm not ready to spend $149.99 (for large) or even $129.99 (for small) thread dispenser. Think I'd like to hear some reviews from nationally known reputable quilters.
