I previously bought one box of these and was concerned because they were different from OEM Brother LC51 cartridges (e.g. slightly shorter, different design, etc.). But after using them, they worked fine. I've been so happy with them, this time I ordered two boxes! They are so much cheaper than OEM cartridges and do the same job. Shipping was very fast.

Was concerned when I received these cartridges for my MFC-665CW as they are different from the OEM Brother LC51 cartridges (e.g. slightly shorter, different design, etc.). But I bit the bullet and put one in. Other than asking me to verify the colour of the cartridge (it doesn't do so on an OEM cartridge), it did install and seems to be working. Will be very happy if I have no problems as these are much cheaper than OEM cartridges.

Just as good as original brand, if not better. Very reasonably priced as well. I always buy this brand.

Très bien

product as described - highly recommended

Great stuff but my printer pores all clogged up because I haven't used it for a while. Not the cartridge fault.
