Review on 🔧 LotFancy 6-Inch 6-Hole Sanding Discs, 100PCS Assorted Grit Sandpaper - Random Orbital Sander Sandpaper, Hook and Loop Paper by Kevin Mills

I haven't used them hard enough to wear them down so its safe to assume they're durable and long lasting (they're pretty much the same for something like this). These are velcro sanding discs, but they don't come cheap. The sanding stays on the pad and I didn't notice the abrasive tearing the paper, which can happen with cheap sandpaper. I have used both 3M and Mirka discs and think they will work equally well. I've been using self-adhesive pads for many years and recently switched to them. If you use self-adhesive film, then it's worth it.
