I have ordered many toners from other manufacturers and I have to say that this tone is worth the price. I've never had a problem with cartridges spitting out toner or not working when installed. They've always worked great, no issues, and they print darker! You won't get as many printed pages as the official toner, but these toners are still cheaper to buy. I will continue to buy from this company as this is not the first printer I have purchased toner for from this manufacturer. This is my favorite so far.
