Review on Do It Wiser CLT-503L Compatible Printer Toner Cartridge Replacement for Samsung C3060FW C3010DW C3060, 4 Pack - CLT-K503L CLT-C503L CLT-M503L CLT-Y503L by Chris Morales

Two cartridges were slightly damaged in transit. The company was very responsive and although I told them both are working now they offered to either replace them or refund my money. You can not ask for more. My wife is an assistant professor at our local art museum and often prints copies of artwork. She says, and I agree, that these cartridges produce more accurate colors than the original introductory cartridges that came with the printer. When it comes time to order a replacement, Wiser cartridges are our top choice.
