very fast delivery, simple installation, decent price, perfect print quality on our HP Envy 5032 and would certainly recommend to anyone. Better than any others we've tried in the past.
By Andrew Barratt on 9 October 2026
These one brand are super value - no problem with HP comparability - if printer says not HP cartridges you can just ignore and when it says ‘ink low’ you’ll find you’ve still got plenty left! Fed up with overpriced manufacturers replacements and coupled with super fast service I can’t recommend Cartridge Save too highly!
By Kate Hickson on 22 September 2026
Brilliant product, really good quality and amazing capacity. Quick delivery and replaced a cartridge immediately when I had a problem.
By SALLY GREEN on 15 July 2026
Used with HP 5020 printer: all round excellent. Would not go anywhere else for my cartridges as it would be very hard to beat the price and quality. Would certainly recommend to colleagues - easy to install, prints out numerous pages beyond the number stated. All with an excellent back up service just a call away.
By SALLY GREEN on 15 July 2026
HP 5020: All round excellent - several repeat orders. Very keen price giving clear print usually over double amount of pages stated. I have and will continue recommending this product - hard to beat especially with such fast, reliable delivery and superb back up service only a phone call away.
