It is very good value for what it is. I prefer a heavier stronger paper a little brighter. But this is fine for the price. I print 300-600 legal pages per week and my printer likes it.
I bought these for personal use at home; mainly for grayscale printing. And I found them just as good as some more expensive brand names that we use at my office. No complains.
We use this product daily for nearly all of our in-office printing needs. It's bright and durable and works great. Is only a 20 lb though so not neccessarily professional document/presentation weight. It just depends however on what you are looking for.
