Perhaps the fault of bad luck! The capacity was less than 700 pages for the first toner. A print everything more standard has to be 5 to 10% filler by page. The second is in the printer. Hopefully the result will be more conclusive. Make attractive prices is one thing but guarantee a result equivalent to a brand toner is another. I do not think I renew my purchase if the second toner produces the same results. So for now, I do not advise.
