These work great in my Dell C1765NWF. I don't see any diminished quality when printing and receive no errors about incompatible accessories. This was my second set and quality remains. Estimated life seems accurate based on my print counts.

We use these for our work we buy 4 of them every 3 months or so. They fit perfectly never have issues with the printing. Just watch out when you remove the adhesive that the ink doesn't splash all over the place.

These worked great. I cannot distinguish between the original and these cartridges in my Dell C1765nwf. I am going to order from them again.

Only used the black toner from this set so far and it's working without any issues on my Dell C1765nf printer. I followed the instruction to shake 5-6 times before installing the toner and it worked. I only use my printer to print a couple of pages per da

The price can't be beat and so far has been well worth it however I have notice the black tends to double up words when printing large volume copies. If printing small batches with cool down time in between it works perfectly.

Works like the original. Haven't run it to the end to see how long it lasts yet. 3 more words

Thank you love it it did did not take long to get them i will get some more when I need them
