Doesn't measure up to its equivalent grades of paper
Sanding a door, and needed this to get into the more difficult irregular areas. They NEVER did the job, and don't compare in grit to paper sheets. I have used similar products successfully in sanding joint compound, but on a tougher job: useless.
Pros
Love these !!! I sanded cabinet doors and it was easy to get into the small tight areas.
Cons
The product may not be suitable for sanding hard-to-reach areas due to its sponge-like texture
