I was having a difficult time finding heavy grit 9 inch sand paper for my power sander. The big box stores only carry light grit paper for drywall mud sanding. I needed something heavier for sanding latex paint and knockdown texture to prep for skim coating. The 60 grit worked great and saved me a lot o time and effort. I would have given a 5 on value, however, not shipping from Amazon, the cost to deliver was almost as high as the product. Other than that, I was very happy with the customer experience with 2Sand.
