Review: A good value - A good price for what may be a lifetime supply for me. Have only used a couple of times but they appear to be well made and durable. Personally, I would prefer a better mix of grits as there are way more coarser grits than I think I will need.
Review: Great price, grit variety and work fantastic! - Work great on my grinder. Love the variety of grits available. Durable enough that it took only one 60 grit disc to remove several layers of oil based and latex porch paints from a porch that is likely original to our 135 year old home. I tried sanding this porch with my Makita orbital sander which was taking forever, then tried a belt sander which just shredded the belts...but these discs made very quick work of sanding this old porch down to bare wood. And you get ten discs for only a little more than the cost of one disc at the big box stores. Highly recommend these and in fact, my neighbor bought them too after seeing how good they worked on my porch.

### ⭐⭐⭐⭐ Are they worth the cheaper price?
*by S***N on December 3, 2025*

I just removed the mill scale from a 20' stick of 1x2 rectangle and quickly burned through the 1-120 and got through maybe 1/4 of the stick then jumped up to 60 for the remainder of the stick. I don't feel they did that great of a job, so is the price a good value for all the flap disc in this purchase. Not sure, but I'll burn through them pretty quick and then compare a different brand before purchasing these again. Not ruling them out 100%, yet.
