It is good and cheap paper. I use it for printing b / w document with a black / white laser printers from HP and am completely satisfied with the result. If both print no complications occur, the pages reserve after the first printing still their form, which has a straight feeder when printing on the back provides lists (with paper from a different manufacturer, I had the problem that curl the pages after the first printing / have curved, with the result that the paper was often skewed).
I recommend the purchase of this product, due to its quality and favorable price.
However, a negative comment I have to make, the package is very poorly protected, you do not provides the board with an extra carton or other protective elements. He is shown in the photo, while a few laps tape. Conclusion: Whether damaged the paper arrives, so will depend on how carefully the postman deal with their package. Fortunately, no damage to my product were observed.
