Highly recommended. We'll be getting another one as soon as the page count hits 7500 on this one.
PROS: This is the third cartridge in our Samsung ML3051N printer and the one that's lasted longest with best print quality. The other two were the original (which lasted about 2200 pages), an OEM extended use replacement that lasted about 4100 pages. This one's been in service for two years and we have over 6500 pages through it with no noticeable deterioration in image/print quality. Most printing has been with the toner saving feature disabled.
