I was sanding a 2' x 3' cutting board project (actually I think it's more of a small countertop) and I was running out of my regular discs. Since I couldn't get them fast enough, I was able to get this product with a 1 day shipping day. I will definitely buy them again! Graininess is precise and feels the same as the rest of my discs. They held up well on my random orbit sander and bounced off from time to time, but that was after using the pad which had probably reached the end of its life. However, I was a bit surprised that they didn't last as long as other brands I've used. I don't know if it has to do with the grinding method or something else, but I just felt like I was wiping the pads faster than I expected. However they were quite cheap so I have no doubts - I would very much like to buy them again.
