Great Product excellent Service I am on my fourth Laser Cartridge over the past 18 months and I have found the LD Product to meet the life expectancy and quality of the original manufactures product. Service and promptness of delivery have been excellent. I had one occasion to test the 100% Guarantee, and it was exactly as stated. My problem was addressed immediately in a professional and courteous manner. A 5 Star Company. February 10, 2014

Flawless substitute LD laser cartridges have worked flawlessly in 2 Samsung printers; I keep ordering from them since they are about 30% cheaper than the name brand cartridges. September 30, 2011
Samsung toner cartridge I have received the product on time but I have not opened yet for use. From my past experience the product would be a quality. Thanks. September 22, 2011
Good Value Purchase The cartridge is great. It works just as well as a new one from Samsung but at a fraction of the cost. This was my third on from LD products and I will continue to use them. April 7, 2011
SCX-4521D3 I have ordered this toner cartridge several times from LD Products and have been completely satisfied each time. I was glad to see the price come down even further since the last time I ordered, even though, compared to $80+ for a new one, even the old price was a huge bargain. They will continue to get my business. March 17, 2011
