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 our own-brand cartridge. This is regardless of how old your printer is. We can afford to offer this as problems are almost unheard of.
Your printer warranty is safe
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, 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.

Have been using Cartridge Save toner cartridges for about 4.5 years now - never had any problems. They always provide great quality results for a fraction of the cost of the official toners. Delivery is very quick, which considering it's free is amazing. Highly recommend this company and their toners.

CartridgeSave really do live up to their word. I had an issue with a cartridge I bought over 2 years ago and they replaced it without quibble. Cartridges came with a 3-year warranty, so it was really good to see my issue sorted quickly. I would recommend CartridgeSave to anyone needing top quality products and customer service.
