i tried it and when i used their sample (small quilt sandwich) it worked wonderfully.
i went back the next day with a 60x60 quilt and it was terrible.
the platform is too small for such a large quilt, it weighed it down - making it hard to move around.
i played with it for over 2 hours and i could never get it to work properly - even the owner (who is a 35 year experienced quilter) could do a feather with it.
needless to say i walk out and didn't buy it.
it would be great for small projects (wall hangings) and quilt as you go blocks.
