I have MS. DH bought me the Go with all the dies available. We just returned it. By the time all the prep work was done, I could have already cut WAY more by hand. The Go wasn't really meant to cut more than two layers of folded fabric, meaning four "slices" for lack of better terminology.
The whole thing took up far too much space, and as far as I was concerned, was more of a hassle than it was worth. Money wasn't the issue, but not being WORTH the money paid WAS. Cranking that handle can sure cause you shoulder issues.
What one loves, another despises. JMHO.
