Dear customer, Thanks for your kind reviews and sorry for this inconvenience ! Could you please contact our customer service for help if have any concern ? We are more than happy to help you here. Best regards,

According to the package,these cartridges are enough to give you 300 pages,I am lucky if I can get over 50. There is definitely something wrong some place.Maybe a bit of false advertising ? I have a brand new Brother printer and these are the only cartridges I can use or I would have switched already. Very,very disappointing !

Dear Customer, Thank you for your review. The page yield is at 5% page coverage. cartridge use is by how much toner is placed on each page printed and how many you print. Depending on your printer make, model and cartridge size along with toner coverage per page, determines how many pages you'll get out of it. If you are printing photos your page coverage is close to 100% and the number of printed photos will be much less than the amount the number of pages you would be able to print if you were just printing standard text documents.
