Toner bought a printer ML 1665. Order placed on July 2 received on 7 July: very fast delivery! Packaging ++++ After reading some negative reviews we still gave it a shot because we noted that we could return the product and we are not disappointed! At installation, this printer does not recognize the cartridge. We turned off the machine, open the hood, and lightly pressed move the cartridge into place, started again and there: impeccable! As my husband said "this is great art!". Printing is nickel. One more thing: if like us, this is the first change of toner, do not forget to remove the protective cover and paper tab on the cartridge if it will not fit in the printer and can give an impression of too wide and too long for the device. I really recommend this product! Big savings considering the price of the product mother ....
