Use it when
The fit is obvious.
- · Choose sheets when you want the cheapest, simplest way to work edges, corners, trim, and one-off repair spots by hand.
- · Choose sheets when the goal is control, not throughput, and you want to feel each grit step as the surface changes.
Skip it when
The job asks for something else.
- · Skip sheets when you are flattening large panels all day and a random orbital will keep pressure more even.
- · Skip sheets when dust collection, speed, and repeatability matter more than hand feel.
- · Skip it if you are solving a very different stage of the sanding sequence than this product was picked for.
- · Skip it if you already know you want the premium option and do not want a compromise purchase.
