Had bought a generic toner that totally messed up the inside of our printer. Got it all cleaned out and original toner installed. Seemed to run out sooner than expected. New toner looks perfect. Just hope it lasts.
This is the second set I've bought since I got the printer that uses them. Didn't give 5 stars because I thought the first set would last longer. Print quality and sturdiness of HP cartridges is unequaled.
