Pros: I have many of these at multiple customers offices. They work great!

Cons: None

Overall Review: Always use genuine HP cartridges in your printers!

Pros: Works, just that simple.

Cons: Note: 90X is NOT the higher page count version of 90A!!

Pros: -Usually get above average yield. Across 10 samples we are averaging about 26-30k pages. Approximate rated yield is 24k. -Dual packs a better value than the single packs. -Have not had any toner failures in the last 20+ cartridges.

Cons: -Price for ink in general is insane.

Pros: Works as advertised and expected. HP (manufacturer) quality is the best choice.

Cons: Price. Newegg has the best price, but HP prices are still considerably higher than competing 3rd party brands.

Overall Review: After ruining a printer with a 3rd party brand, I learned my lesson about low-priced 3rd party "compatible" knock-offs.

Pros: Price, works

Cons: None
