This is decent sandpaper: not the best, but not the worst. Its grit retention is average while its paper backing is fairly durable. I don't expect a lot from 80 grit paper since it does receive a good amount of abuse in normal working conditions. It is sized right to fit my sanding tools. So, if you are looking for 80 grit sandpaper that can do the job without breaking the bank, this is a great choice.I would have rated this at 3 stars for being average quality; but because the price is good, I bumped it up to four stars for its economic value compared to quality.
