Review on LotFancy Assorted Flap Discs Set - 20PCS 40 60 80 120 Grit Grinding Wheels, Type 29 High Density Jumbo Flap Sanding Wheels with Aluminum Oxide Abrasives by Julio Solano

Only the 40th grit is 11mm, all others in the range are 5mm. False advertising. UPDATED: I was told they would rewrite the ad to correct the misinformation and was given a $10 credit for the product. UPDATED: Use 40 grit today, wears out quickly and is not good for smoothing welds. . It's too soft, the disc's sandpaper bends around the weld and sands the metal on the edges before sanding the weld. It cleans well from oxidation, but wears out quickly. Branded wheels for me on the go.
