We have used this paper for at least two years without problems. We always order online and have never had to drive to Staples to pick up a box. We use it in our networked Printer/Copier/Fax as well as a few inkjet printers. We push at least 5 000 and up to 10 000 sheets in busy months. Very clean (little or no paper dust) and I have had no paper jams due to the quality of this paper. Our copier speed is 30-35 pagers per miniute. After two years of use and more than 200 000 sheets I can highly recommend this paper.
The five ream package of copy/everyday use paper is convenient for me because it combines a significant amount of paper in a package that is easy to pick up and carry. The regular 10 ream case is too heavy subjecting most people to the possibility of straining their back. Also unless you need for the box the ten ream's packaging is a disposal problem.
