I've been to a demonstration of the system but I haven't bought it since I haven't been making clothes too much in the past 10 yrs. From the reviews I've found it seems to work fairly well although I don't think it has assembly directions. You know....pin sleeve to armhole easing it in...type of thing. You need to already know how to assemble the pieces after cutting.
Someday I'd really like to buy it.
Let us know if you get it and what you think of it.
