my daughter is a frist year teacher,and coach.She told the school distirct where she works only buys them one color,and 1 black ink cartridge per year.She was prepared to buy new ones till we found them on overstock.com .for the money she saved.She will always buy from overstock.com

Cartridge worked immediately without problems. Hopefully it lasts!

I haven't used these a whole lot, but so far they work great. I figure I saved 2/3 of the cost of the cartridge. I bought remanufactured ink cartridges one other time from another source and the colored cartridge was a mess. The colors were all green. A very good buy. Now, to see how long they last......
