    By Suzanne Fletcher on

    We had been really pleased with the ink cartridges for our Epson Workforce Pro WF5110, a good price and very prompt delivery. We started using them when the printer came out of guarantee. However the print quality on any block of printing, like a photo in a document, started to get lines on it, about 8 months ago. We thought it was the printer playing up and did everything we could like nozzle cleaning. the black for the written word was getting slightly fainter too. We are now having to replace that printer (complicated why - we had an old HP printer that was a scanner too, and it has "died" of old age probably - but excellent printer quality with the Cartridge Save inks). The Computer shop we use, and are ordering our new printer through ( and has no vested interest as they do not sell ink) has said that really we should not have been using a compatible ink as the true Epson one's has an inbuilt cleanser, that maintain the nozzles. So we will be buying the Epson inks when we get the new printer (but would anyway whilst under guarantee) for it to maintain ink quality. this does not detract from us rating Cartridge Save for price and service.

    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.
