Been using these toners in my Canon printer for a few years now. Have not encountered any problems and would highly recommend. One of these toners lasts for about 6 months and we are a somewhat busy office. I find it very economical.
I don't even think about this product. It works just as it is supposed to without any problems. Have ordered it for 3 years now. Love having the savings and not having to sacrifice!
Our company purcahsed several new Cannon 120 printers here in the last few weeks to use in our shipping deapartmnet. So far we have been pleased with the the toner cartlidge and its life. Before in the past when we were using another printer that required a different printer we were purchasing toner cartlidges every week. Our consumption has decreased tremendoulsy.
