[This review was collected as part of a promotion.] Like all of HP's inks and toners, the toner cartridges themselves work great. The color quality is great. I use the printer that these toner cartridges are installed in at home, and I've gotten several years of use out of the original toner that came with the printer. The only thing that keeps me from rating this with 5 stars is the high cost.

[This review was collected as part of a promotion.] This set replaced the original cartridges in my Color Laserjet M452 model. The process of replacement was very easy, and a print of the demo page showed that the new cartridges were all operating properly.

This is a wonderful toner cartridge! It fits in the slot in my printer perfectly, feeds like a champ and tastes wonderful. Downrated to only three stars because the smell is slightly off, altough it seems to print the correct colors whenever I ask it to.

I tried to use third-party supplied toner cartridges many years ago and they caused our small company nothing but grief with smeared pages. The HP OEM cartridges never give us problems but the price makes no sense. We previously bought all four cartridges at the same time and kept our own stock but now they are too expensive. The two cartridges together cost more than the original price of the printer. How can that be. No competition I guess. Free enterprise at work, maybe.

Even thought I print just for the house for personal use, I wanted a more lifetime or high yield toner cartridges. Because they cost a little more than the regular toners, I order them one or two at a time. Thank you for your product. I still have one color to order yet. I will order it soon.

Purchased ink refills and these were sent promptly and I had no problem with them, In addition I purchased a Microsoft program (365) and somehow (my error? perhaps) and the email I received from HP for securing it to upload, etc. was lost. Requested a second copy of instructions and have yet to hear squat.

[This review was collected as part of a promotion.] My last toner cartridge left black marks on the page from top to bottom, and now the page prints clean with the new black toner cartridge installed. Now to wait until the cyan one runs out to see if replacing that one will get rid of the cyan marks on the page when I print in color!

I ordered a high-yield black toner cartridge on Thursday Feb 4, 2021. Delivery was estimated to be 2 to 10 business days. I presumed the actual date would be near the beginning of that range. Following its progress, spending a couple of days the Minneapolis area, then a couple of days in the Kansas City area, then a couple days in the Denver area, before arriving at my house on Saturday, Feb 20. Maybe Federal "Express" needs a new name? Robert Mohrbacher

I have purchased several cartridges and only one has been defective, leaving marks on the document. Otherwise, this printer is amazing. The only downside is the cost. They are very expensive and had I known how costly the printer would be to operate, I might have looked at a different machine.

[This review was collected as part of a promotion.] I bought my HP laser printer 2 years ago and this is my first time replacing the black cartridge. The printer is a little pricey up front, however, the HP technology, quality and ease of use makes the HP laser printers the best value available.
