These replacement ink cartridges are fine. I'd say they're moderately easy to install, once you realize which door on your machine to open. I like them because I'm an average user of my home copying machine. I neither run a business from home, nor am I a luddite. Like may people, I simply need "one-off" photocopies from time to time. In addition, there are between two and four times a year when I need many copies all at once. As an amateur musician, I'd say three to four times in a year, I need to photocopy and print significant amounts of sheet music (yes, I pay the copyright holder). And let's not forget the copies needed at tax time. The thing about these cartridges is that they contain a great deal of ink. Despite my "heavy use three or four times a year, I generally have to replace the cartridge only once a year at most. They never last for two years, so I'd say the average is about a replacement cartridge every 15-18 months. They are always at the ready, even after a long period of no photocopying at all, the very first page printed is a good as any of the pages throughout the run. That's a type of technical feat that had to be difficult for the engineers and scientists at Brother to figure out, and for which I'm very grateful, as the casual user of printing services in-home.

It usually takes me 10 months to a year before I replace the cartridge for my brother printer. Recently for the passed two times I replaced the cartridge which gave an average use of three months,I notice inadequacy. During each replacement the notice Low in towner pops up. It became a concern when my credit card was charge for a new cartridge and product shipped to my home. My printer is for home use and this observation of cartridge deficiency altered my perception of this product functionality. I'd wish to receive in future the proper benefit from the cartridge ascribe
