Seems to work just fine. I am not into enough to determine it's long term quality. I didn't see anything in the instructions to remove the two tiny orange plastic pieces on the ends, so at first it was not fully seating and was printing off fully black pages. I had to figure out the orange throwaway pieces on my own.

This is a very good product. The toner arrived on time and was the correct fit for my all in one. The copes are we collect and they have not Jamed in the 3 weeks that I have been using the cartridge.

A++. Excellent product and very fast shipping! I need to add 13 more words, just a couple more will do.

Awesome for the price. Works great in my printer and saved lots of money. Packed in very nice box.

It worked after I reset alarm on printer (to ignore non-brands...). Reasonable performance. Good price, good customer service.

just as good as the name brand product but MUCH cheaper

Great price, great service, great toner

one of my toner cartridges RS-MLT-D105L only lasted about 100 copies before running out of ink. it should last more than 1000 pages. the other seems ok.
