Review: Great Cartridge, best price I could find anywhere, too! - Worked great - just like an OEM toner cartridge should! I couldn't be happier! I have tried a few other non-OEM toner cartridges, with mixed (usually bad) results. Of course, this toner cartridge costs more than the rebuilt/refilled units, but it has already given me a few months of trouble free service, and I expect it will continue for the life of the cartridge.
Review: Great product and cheaper than staples.com - I use these toners in my HP5500n workhourse which has never been rebuilt and has been working for 10yrs now almost everyday. I do shut it down during storms and on weekends to give it a break.

### ⭐⭐⭐⭐⭐ Expensive, but the real thing
*by J***H on July 6, 2012*

I'm going to review all colors for our HP Printer right here. They are expensive, but we NEVER have problems with them and wouldn't consider anything but the real HP laser cartridges.
