I just bought one at a local quilt show. I saw it a couple of months ago at another and waited and thought about it. I bought it 2 weeks ago and yeah it does help. I am in a wheelchair and have a hard time getting my material arranged on the board and not messing up what I just pressed. With the stick it isolates the seam and allows me to work on just the area I want. If you are pressing a seam open it is great too.
I bought a package deal with 2 sticks (18" & 45") and a Seams Sew Fast Guide for $29.95
