So far, I notice no difference between original and this replacement. Hopefully, the useage period will be about the same. Great company to work with. Will use again.

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.

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.

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.

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.
