Review on 🖨️ ColorPrint Compatible 504S Toner Cartridge Replacement (5-Pack) for CLT-504S CLT504S K504S CLT-M504S CLT-C504S CLT-Y504S - Works with CLP-415NW CLP-475 CLX-4195FW Xpress C1810W C1860FW - 2BK 1C 1M 1Y by Pat Nard

I ordered these toner cartridges a bit skeptical as the reviews varied. But given the warranty upon purchase, I tried them. I wanted non-OEM cartridges to replace my Samsung cartridges. I replaced all four cartridges and the printer recognized them with no problems. The toner level is determined by the program. The print was clear and precise. I can't comment on cartridge durability, but in my experience the printer degrades when about 10% remains in the toner cartridges. Even after shaking the cartridges. Let's see how they behave. Delivery was fast.
