Great product!

This company is awesome! You will love making a purchase from them because you can trust that they stand behind their product! So, go ahead purchase and print and buy again and again. That is what I plan to do! True Image has got you!

This is a great company with truly excellent customer service! I have bought their replacement toner for my HP printer. It works great & I would not hesitate to buy from them again.

If you do a lot of printing, it won't cost you an arm and a leg!

Work greatly with my Canon D1320. Print quality is sharp and clear. Highly recommended.

This black toner cartridge set is a budget-friendly alternative to HP’s OEM toner, designed for LaserJet Enterprise M507 and M528 series printers. It provides substantial cost savings while maintaining crisp, professional-quality prints with smudge and fade resistance. Additionally, the high page yield (5,000 pages for CF289A and 10,000 for CF289X) makes it an excellent choice for offices with high-volume printing needs. Its easy installation and seamless printer recognition ensure a smooth experience, making it a convenient drop-in replacement without requiring special setup.However, potential firmware update issues pose a risk, as HP frequently releases updates that may block third-party cartridges. While this toner works well now, future updates could render it non-functional, requiring users to disable automatic updates or downgrade firmware. Additionally, some users report slightly lower-than-advertised page yields, meaning it may not always match the efficiency of an OEM cartridge. Enterprise security settings in certain printers may also flag it as non-genuine, triggering warning messages, which could be a concern for organizations needing seamless compatibility and support.For businesses focused on cost reduction, this 4-pack bundle is an excellent value, offering similar print quality and performance to HP’s version at a fraction of the price. However, those requiring absolute reliability, long-term firmware compatibility, or OEM-backed support may find it less ideal. If your printing needs are high, and you're open to occasional firmware management, this compatible toner is a smart investment, but if you prefer zero risks and long-term guarantees, OEM cartridges remain the safest choice.

Product is as described and works as good if not better than the HP for alot less cost. I appreciate the availability of compatible products.
