Aztech 26A CF226A M402n Compatible Toner Cartridge Replacement for HP 26A CF226A CF226X for HP LaserJet Pro M402n M402dw M402dn MFP M426fdw M426fdn M426dw Printer Ink (Black 4-Pack)

At first I was skeptical. I thought, how can they do this at this price. So far, so good. No bleed outs, dirt, lines, spots, or fuzzy output. I can't distinguish the difference in quality from the original included brand's cartridge that came with my printer, from this one. And that's a good thing. What will matter to you is the rated page count per cartridge. Although these toner cartridges gave a lower page count output, overall as a bundle you do far better with this bundle in price and overall combined page count output with the four of them, in my humble opinion. We all like saving money, getting a good deal, and great quality. This is the one!

Didn’t fit however it was easy return

These cartridges are a great alternative to the pricey HP ones. We rarely if ever have a problem with one, and if we do, sellers have been great at exchanging them.

Works as advertised. I'm impressed with that. So many of these off market cartridges can have issues. will definitely buy again.

I have purchased this item numerous times, and they have always been great. The most recent purchase had 1 defective cartridge. I sent a message with a picture, and they promptly sent out a free replacement. Top notch customer service!

This HP ink never lets us down. Fast shipping.

UPDATE TO REVIEW: 4/28/22 - The seller recognized my negative review and notified me of a problem with some of the cartridges... They offered us replacements for the trouble. I did not expect this and am very pleased with how this situation was handled. This is an example of very good customer service and shows that they stand behind their products!! Initial review: I was really excited to try these toner cartridges because they are a really great deal and the last cartridges I received from a different seller on Amazon weren't the best. Unfortunately, after I installed my first cartridge today, March 28, 2022 I noticed the paper has a gray tint to it. More noticeable around the outer part of the paper but you can definitely see a difference of the clean paper put in and the printed paper. I'm really not sure why it would be leaving this tint except for the fact that it is defective.

I use a lot of toner so I am very thank to have found these cartridges at this price. The print quality is great which is very important for my business. The price helps me keep my cost low so I have a better profit. I recommend these toner cartridges for anyone who prints causally as needed or in a high demand of print with great quality.
