I used to manage the IT department of the hospital. We tried 4 different brands of 3rd party toner cartridges and all 4 failed. We have returned to corporate style. These things work. Just like this one. I swear it now I tried another remaining brand and had a terrible experience. I returned to them and life was prosperous again.
