Review on LotFancy 5 inch Sanding Disc, 100PCS 60 80 120 150 220 Grit Sandpaper Assortment, Hook and Loop Sand Paper, Random Orbital Sander Pads for Optimal SEO by Ben Jacobson

I have been building kitchen islands, chopping boards, stools, benches, tables, toys, art and many other woodwork items for a number of years now. Years old and I'm sorry to say this is the worst type and brand of sandpaper I've ever used. Very poor cutting wear, none of the grits in the range cut very well. Each disc was used less than 5 minutes before I had to switch discs. Some failed even earlier because the hook and loop base just lost grip and let go of my grinder even at low speed and I couldn't reattach it. Other grinding discs I have in the shop work fine with the same tool, this is not my tool. This is the most disappointing product I've bought in years. I'm not sure given the other rather positive reviews of the same product, but maybe I just received an old or bad lot/batch of discs? All I know is that my hard earned money, the amount, doesn't matter because every amount of money spent on performance that doesn't produce results has been wasted on grinding wheels that I will never use.
