These are the best unbranded replacement toner cartridges I've tried. The density could be better, but is quite acceptable. I haven't finished the first cartridge but judging by the specs of my printer I don't think I'll get as many pages as brand name toner. However, and importantly, the cost per page is about 1/4 the cost of branded toner. So, yeah, I might have to open up the printer and put the toner in a little more often. A minute of my time to save all that money? Yes, please.
