6-Inch 49-Hole 220 Grit Sanding Discs - Heavy-Duty Hook & Loop Film Discs - Sandpaper for Random Orbital Sanders - 50 Pack Box

4 could be a five. Just have not used the product as of yet. These look just fine and really, the price does matter. So, these sanding discs will be put to work soon enough. Oh, I'll change to a five now!

These sheets don't last as long as the Festool sheets but they are probably a good value for the price difference.

This product did the job, but did not cut in as aggressively as I thought it would got the job done but took a long time. Not sure what I think.

Worked as well as the festool paper but not well enough to get me to switch off of mesh paper.

The performance is equal to the performance of the festool paper

This company has an excellent product for the money that far exceeds what Festool provides. Festool has a great product as well but at a much higher price and it has a paper backing which is not as durable as the poly/plastic product that Serious Grit makes.The poly/plastic backing is more expensive to produce but it gives the user a sanding disk that has greater strength and durability.

Seems about on par with other similar 80 discs.

Haven't used it yet.

I was expecting it to be thicker and last longer. I need to use 3 pads for the same time of using 1 pad of the original pad that I had with my Festool sander. Still works but just doesn't last long...

I find these disks to be as good, if not better than the Festool and Makita disks I have been using. I use them on a Festool 6” rotex sander. The disks don’t have as many vent holes as the festool disks, but it doesn’t appear to make any difference with dust extraction. The paper stays just as clean as the festool disks. The Serious Grit disks also cut and wear well. I expect to get just as much or more life out of them as any others I have used. Great quality, great value.

Item arrived as advertised. good value.
