HP makes the best printers and toner cartridges. My printer is pretty old, but no issues whatsoever with messy toner leaks. Copies are always perfect.Within the span of one year, I have had two HP Cyan cartridges fail (they leave a ragged blue border on each page printed). Given the extortionate charge for this product, one would think that they could be relied upon not to fail out of the box. If one should think that, they are grievously uniformed.HP toner is as expected. A good product and great color . Like that you can return them to HP at no cost. I just wish they weren't so pricey. Was debating on trying a cheaper brand but after reading about some of them decided to go with the pros.Tried the generic cheaper toner cartridges...and you get what you pay for. Nobody is thrilled that the genuine toner cartridges combined likely add close to the total cost of a new printer...but I like my printer and bit the bullet. Prints are nice as expected unlike after a few weeks with the generic toner.These cartridges print about 7500 pages or so. They are half the cost of the old toners we used to purchase from HP and a lot easier to install. They also come with a prepaid label to return the old cartridge instead of sending more plastic to the dump.Be careful on which printers this works for. If you zoom into the image, you will see on the front of the box which printers this works on.Works great and costs less here than at Office Depot.Works as advertisedExcellent toner for HP LaserJet printers. I use the original cartridges for my HP LaserJetPro 400 Colour series printer.The product is exactly as described, and was dispatched rapidly by the seller. These cartridges certainly do provide the advertised print capacity, but beware that of course heavier printed pages will obviously use the cartridges more quickly.I would always recommend the HP originals, even for the extra price - the cheaper versions are more likely to fail, may leak toner, and never can print as much anyway.Needed the reliability and quality of an original HP toner. It works/prints just the way you would expect a genuine HP toner to print.as expectedThis item was bought in February but only just got round to needing it. When opened it exploded blue ink everywhere. Now it appears I can't return it.Great product - I can recommend...
