Been using flap discs for the last 15 years and these have been the worst for longevity. Yes, they are about 3x less expensive than higher quality brands but don't last even a 1/3 as long. I've put them in a cabinet as emergency backup in case I run out of my preferred brand, otherwise I won't even use these.
