Review on JUEMEL 5-Inch 8-Hole Hook and Loop Sanding Discs - 160PCS Assorted Grit Sandpaper (1000/600/400/320/240/150/120/100/80/60) for Random Orbital Sander - Ideal for Woodworking Projects by Narendra Thapa

Quality appears to be good but has never been tried as the sandpaper is 4 3/4 inches instead of the advertised 5 inches. I have a Bosch ROS20VSC random orbit sander and the paper that comes with the 5 inch sander is supposed to be that size but it isn't. I tried to double check a part to check the size that stuck well to the disc but it was such a hassle to line up and align the holes that barely covered the bottom. So if you hit the edges at all you're going to ruin the foam disc and you'll have to replace it. It's not worth it so I went back to the Mirka brand and it's 5 inches indeed!
