GOOD: Toner longevity is great, doesn't dry up if not used (purchased this 4 years ago). Perfect for those of us that don't print items every day. BAD: This cartridge printed only 75% of it's stated 1500 pages; my printer report shows 1134 pages printed, with 1% toner remaining.
Based on this, appears I paid for 100% of something and received only 75%. I will search for alternatives before buying Samsung toner again.
