| This product is easy to install and delivers the quality that I rely on. I bought my HL-1870N printer which came with one of these TN-560 cartridges, and I got 6200 pages out of it according to the network administration function. It tooks several years. I had bought a spare toner cartridge in anticipation with the printer, and it sat on a shelf for years. I fully expect it to last another couple of years. Some people complain about everything. As previous reviewers suggest, keep in mind your usage versus the 5% standard rating. If you like to print web pages, other graphics, etc., you will use up the toner in a hurry. That goes for any printer. I got 4500 + copies from my first cartridge, which was mostly text and some graphics. I am very pleased. |
