I am new to sewing, so am stocking up on little accessories and gadgets that I think may help me, and these appeared to fit the bill in that context, but they don't, I may have been expecting more from something that was supposedly adjustable, so this must be a new definition of the word adjustable that I have not previously been aware of, there is barely 1mm to 2mm of movement available, not enough in my mind, but they appear to be similar compared to other versions of this foot, so maybe I am expecting too much. I probably wont use them, I can pretty much do a rolled seam by eye now, ah well, you live and learn I guess.
