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.

Easy installation, great price, can’t fault the print quality.I am using this cartridge on Brother MFC-J870DW. I buy all my cartridges from cartridgesave and find them as good as the original Brother cartridges. Excellent value. Thank you Cartridgesave.
