I purchased a couple of packages and tried them on my Delta. I'd say they work okay if you have fairly large openings to pass the strip through and the edges are either stright or a larger radius. I don't think they work well on projects with 1/8" stock and finer detail work. Finally, unlike when you are cutting and the blades pull the stock toward the table with sanding strips it pulls both directions. Like with most things in life - it's about compromise.
