3M Dust-Channeling Sponges is rated 4.7 out of 5 by 110.
Rated 1 out of 5 by from worst sander for Drywall This is the worst sanding sponge I have ever used for drywall. The dust channeling is just a gimic. The small pads don't stay on the sponge and when they are there, you get a very uneven sanding. Especially on the flats of the mud. Do NOT waste your hard earn money on this piece of ----

Rated 1 out of 5 by from Disappointed I bought the ultra flexible precision 80 grit sanding sponge a couple months ago. I usually am a huge fan of all 3m products that I have used through work and my hobbies. The detailing pads ripped off five mins within use. I wasn't overly aggressive with it just doing some regular sanding on my table that I've been building. Around six of the pads ripped off while a few others are holding on for dear life. Hopefully I just received a bad product and this was out of the ordinary for this sanding sponge. I've never been let down by any 3m product except for this one.

Rated 5 out of 5 by from Multiple uses I got a little creative and went out of the normal usage box: I have used this as a foot callus scrubber. Also, works pretty well when removing accidental marks on a wall that the kids may have marked with permanent marker.

Rated 5 out of 5 by from Very Handy for Smaller Jobs I received this free from 3M, asking me to review it. We have had a few small painting, touchup jobs around the house and found the block extremely handy to use. It sands well, is easy to use, and doesn't get clogged with dust. We have not used it enough at this moment to assess how long it lasts, but so far we have been quite pleased with the performance of the product. We would buy it at our local supplier for future jobs once this one no longer performs.

Rated 5 out of 5 by from it works for me received as a free sample. Used on my front doors which have a lot of detail relief and am very pleased with the results. The Ultra Flexible Sponge got into all the edges and corners of the door.

Rated 5 out of 5 by from So great for detailed areas needing sanding 3M sent me this great Ultra Flexible Sanding Sponge to test out for free. I've been sanding furniture with a lot of detail, including a table with spiral carved legs. The sponge has made it easier to get into the grooves and smooth down the paint, giving me a smooth finish on the legs.

Rated 4 out of 5 by from Good For DIY projects I like to do DIY projects at home and 3M ultra Flexible sanding sponge came really handy to me. First of all, it has dual sides, patterned side and regular side. I painted my table and used it for trimming the paint. I would say, it worked well. I also liked the fact that it is washable and reusable. It is nicely made and of quality material. I recommend them! "I received this product free from 3M to evaluate"
