I have been resistant to use off brand toner cartridges because Office Depot warned me these cartridges could ruin my Brother mono laser printer. I just hate the price of the manufacturer's cartridges. I started to think that Brother does not make their own toner as that is a whole different manufacturing capability so they must contract with someone that does make toner. As it turns out, there are only a few plants that make toner and there is a standard all plants must comply with so the toner is pretty much the same for all brands. The difference is the quality of the plastic housings. I do not know who manufactures Bkey cartridges but I am impressed with the quality of their cartridges. I have printed a 100 pages so far and the prints look great and no feeding issues. At this point I can say I recommend Bkey TN-660 cartridges and I plan to never use the manufacturers cartridges again. I will use the extra money to go to Cold Stone Creamery and buy several "Gotta Have It" sea salt sweet cream with caramel & heath bar pieces ice cream bowls.

These cartridges seem to last along time and the price cannot be beat. They arrived quickly as promised. They are a little messy and come without instructions, but I will definitely choose these the next time I order.
