"I purchased a black refill kit for a Lexmark x83. I received the shipment in two days. I immediately opened the package and refilled my black cartridge. It worked great!!! I could not believe how easy it was to refill the cartridge and how well it printed. I am very grateful for your product and it has saved me a ton of money!!! I am very pleased that I found you. Keep up the good work" (Gayla)
