Review on Cool Toner Compatible Toner Cartridge Set for Samsung CLT-K504S CLT-504S - Samsung Xpress C1860fw C1810w SL-C1860fw SL-C1810w CLX-4195fw CLP-415nw Printer - Black Cyan Yellow Magenta, 4-Pack by Stephen Hobbs

I will not buy this brand or printer cartridges from other brands again. I purchased and received this toner kit in mid-April 2019 for my Samsung C-1810C series printer. At first everything went well. The print quality was just as good as the original cartridges. I was running a print job this past weekend, May 17-19, when black toner suddenly came out of the printer on the left side of the sheets. I stopped the printer and opened the cartridge door. All of the other cartridges contained black toner, and when I lowered the cartridge door all the way down, there was black toner in the door as well. Something obviously went wrong with the black toner cartridge, causing it to leak toner all over the place! Needless to say I've learned my lesson. I will never buy toner cartridges from other manufacturers again! I'll just put my pants on and only buy Samsung OEM cartridges despite the price difference. Rzhunimagu!
