I have been watching this as well. It wouldn't work for me because my embroidery machine sits on top of kitchen-type cabinet so no place for the legs.
I can't give you any advice here, but the demos always look super easy. I know there's a special show price, but I wonder if they have a return policy that will allow you to return it if you don't like it?
I did a quick YouTube search to see if anyone not affiliated with a quilt shop posted a review and couldn't find any. I think it is tough to find a fair review for sewing products.
Have a great day!
