Review on 🪚 Coceca 80pcs 5-inch Orbital Sanding Discs for Power Random Orbit Sanders - Assorted Grits: 40 60 80 100 150 180 240 320 by Gerald Barrett

terrible. I bought these for my mouse grinder and haven't had too many problems. They weren't perfect, but they got the job done (with twice the leaves). Now I bought these for my random orbital sander and they are just awful. I have used at least 4-5 times more sheets than I would use Norton or even 3M brands. Also, I want to go through the bag first. Entire grain regions were missing in more than half of the 40 grain sheets. The white backing was visible from the sand side. I will try to get my money back although I doubt I will as I probably used 10 pads from the pack. Better buy!
