[This review was collected as part of a promotion.] The four toner cartridges I bought are fine and produce quality printing. The only reason I didn't give five stars is because I'm unable to get an answer about why the authentication is not working and can't access the internet. I am apparently not alone in this from what I see in other responses.
[This review was collected as part of a promotion.] I ordered replacement ink cartridges for my HP LaserJet printer on a weekday evening, and selected free overnight shipping. They were shipped and delivered as advertised. You can’t go wrong with authentic HP ink.
[This review was collected as part of a promotion.] The toner/printer is great, but I only gave 4 stars because it took forever to receive the magenta toner cartridge which I ordered from HP. I'm still waiting on the yellow. It has been weeks!
