      No hesitation in recommending and ordering again. Very good value for money for 2,500 capacity. Installed no problem, recognized and accepted by my Oki printer. Black and White quality very good and colour photo quality exceptional, pin sharp. arrived very quickly and packaged very well.No faults whatsoever thus 5 stars for this review.

      By Alan on

      I am very pleased with both the product and the service from Cartridgesave. Which was in stark contrast to the astonishingly poor product and service I received at your rival PRINTERLAND. Who left me without a fully functioning printer for over SIX MONTHS due to faulty OKI drums that they supplied. Finally replacing them only after many appauling stalling tactics.
      They finally settled only if I agreed not to report any faults that may occur with 2 of the 4 products that did not become faulty.

      3-year warranty on our own-brand cartridges
      We are proud of our own-brand cartridges, so we’ve made trying them a no-brainer. If within three years of purchase you have any problem whatsoever, we’ll happily offer either a replacement or a refund.
      Returning items is easy—it takes just a few minutes. But our return rate is very low, so you’ll be unlikely to need it.
      We are confident that no other own-brand cartridges are better than ours. They produce vibrant prints with accurate colour densities and dark blacks—and their page yields are as good as the genuines, if not better. Give them a try, and see why our customers love them.
      Our own-brand cartridges are incredibly reliable for three reasons:
      1. We are the UK’s biggest seller of own-brand cartridges, and we have invested a lot in optimising them.
      2. We are dedicated to quality. Every own-brand cartridge is performance-tested before it leaves the factory.
      3. We constantly monitor customer feedback, and quickly resolve any issues.
    • Printer protection guarantee
      Our cartridges won't damage your printer—guaranteed
      Some people worry that own-brand cartridges might damage their printers. We know from experience that ours don’t.
      To reassure you, we guarantee that we’ll repair or replace your printer—for free—in the unlikely event that it gets damaged by an own-brand cartridge. This is regardless of how old your printer is. We can afford to offer this because problems are almost unheard of.
      Some people whose printers are less than a year old worry that an own-brand cartridge might invalidate the manufacturer’s warranty. This isn’t true. By law, the manufacturers aren’t allowed to invalidate your warranty if you use own-brand cartridges. If something does go wrong, and our own-brand cartridges are to blame, we’ll take over the manufacturer’s warranty, offer you phone support and repair or replace your printer if needed.

      In summary, there’s zero risk in using our own-brand cartridges.

        3-year warranty on our own-brand cartridges
        We are proud of our own-brand cartridges, so we’ve made trying them a no-brainer. If within three years of purchase you have any problem whatsoever, we’ll happily offer either a replacement or a refund.
        Returning items is easy—it takes just a few minutes. But our return rate is very low, so you’ll be unlikely to need it.
        We are confident that no other own-brand cartridges are better than ours. They produce vibrant prints with accurate colour densities and dark blacks—and their page yields are as good as the genuines, if not better. Give them a try, and see why our customers love them.
        Our own-brand cartridges are incredibly reliable for three reasons:
        1. We are the UK’s biggest seller of own-brand cartridges, and we have invested a lot in optimising them.
        2. We are dedicated to quality. Every own-brand cartridge is performance-tested before it leaves the factory.
        3. We constantly monitor customer feedback, and quickly resolve any issues.
      • Printer protection guarantee
        Our cartridges won't damage your printer—guaranteed
        Some people worry that own-brand cartridges might damage their printers. We know from experience that ours don’t.
        To reassure you, we guarantee that we’ll repair or replace your printer—for free—in the unlikely event that it gets damaged by an own-brand cartridge. This is regardless of how old your printer is. We can afford to offer this because problems are almost unheard of.
        Some people whose printers are less than a year old worry that an own-brand cartridge might invalidate the manufacturer’s warranty. This isn’t true. By law, the manufacturers aren’t allowed to invalidate your warranty if you use own-brand cartridges. If something does go wrong, and our own-brand cartridges are to blame, we’ll take over the manufacturer’s warranty, offer you phone support and repair or replace your printer if needed.

        In summary, there’s zero risk in using our own-brand cartridges.

      I originally bought a replacement set of toners back in October but only needed to replace the Magenta in April. When I put the toner in the printer did not recognise it. I rang Cartridge Save and they dispatched another cartridge that afternoon and I received it the following day. The new cartridge worked.

      Very pleased with the product and no-quibble replacement/return (FOC) service.

      I have installed this yellow cartridge in my printer but have only printed in black since it's installation. It fitted and looked similar to original cartridges and expect it will work to my satisfaction. Certainly more affordable than original cartridges.

      By SteveB on

      I order this toner at 3:30 pm on friday it was delivered by 9:00am on the monday, and that was the FREE postage service. I have installed it in my printer and it works great no hassles like you can have with some compatibles.

      I highly recommend this cartridge and cartridgesave.

    • 3-year warranty
      3-year warranty on our own-brand cartridges
      We are proud of our own-brand cartridges, so we’ve made trying them a no-brainer. If within three years of purchase you have any problem whatsoever, we’ll happily offer either a replacement or a refund.
      Returning items is easy—it takes just a few minutes. But our return rate is very low, so you’ll be unlikely to need it.
      We are confident that no other own-brand cartridges are better than ours. They produce vibrant prints with accurate colour densities and dark blacks—and their page yields are as good as the genuines, if not better. Give them a try, and see why our customers love them.
      Our own-brand cartridges are incredibly reliable for three reasons:
      1. We are the UK’s biggest seller of own-brand cartridges, and we have invested a lot in optimising them.
      2. We are dedicated to quality. Every own-brand cartridge is performance-tested before it leaves the factory.
      3. We constantly monitor customer feedback, and quickly resolve any issues.
    • Printer protection guarantee
      Our cartridges won't damage your printer—guaranteed
      Some people worry that own-brand cartridges might damage their printers. We know from experience that ours don’t.
      To reassure you, we guarantee that we’ll repair or replace your printer—for free—in the unlikely event that it gets damaged by an own-brand cartridge. This is regardless of how old your printer is. We can afford to offer this because problems are almost unheard of.
      Some people whose printers are less than a year old worry that an own-brand cartridge might invalidate the manufacturer’s warranty. This isn’t true. By law, the manufacturers aren’t allowed to invalidate your warranty if you use own-brand cartridges. If something does go wrong, and our own-brand cartridges are to blame, we’ll take over the manufacturer’s warranty, offer you phone support and repair or replace your printer if needed.

      In summary, there’s zero risk in using our own-brand cartridges.
