I was very happy with my EZ-Ink purchase, the colors looked good and I had no trouble setting up my brother printer for toner cartridges. Would definitely recommend as not only was the replacement cartridge easy to install - the whole package was great value and the prices for the factory toner cartridges are insane! So it was easy and the colors look great - I was initially worried the colors would be as good as they came from the factory but EZ-Ink proved me wrong - will definitely be buying from them again. I'll try to update this cartridge durability review, but at this price point it was worth the risk - so far (about a month) I haven't been disappointed.
