I would highly recommend this product. It works excellent on our copiers and printers. Unless there is a situation that a particular kind of paper is needed for some reason I see no reason to buy any other kind of paper.
I have used the Staples Multipurpose paper 8 1/2" x 11" . ream paper for many years and find it very good. I especially like the 5 ream case because it is easier for me to handle. The 10 ream case is too heavy and bulky and I have to ask for help.
