3M SandBlaster Between Coats Sanding Sponge, Gold, 3-3/4 in. x 2-2/3 in. x 1 in., 320 Grit is rated 4.0 out of 5 by 4.
Rated 5 out of 5 by from Very effective and useful I use these sanding sponges for the final sanding before I apply a finish. I also use them to gently round over edges. They are very easy and comfortable to hold. They last about as long as regular sandpaper, maybe a bit longer. When they load up I clean them by throwing them on my workbench or vacuuming with a shop vac. Overall I find them very effective and easy to use.

Rated 1 out of 5 by from Short life span For a relatively expensive item the first sponge I used - coarse on a slightly curved piece of driftwood - deteriorated to useless in less than 10 minutes. So during if I ha e missed something I have looked for instructions to no avail. I will return the sponges I haven't used yet.
