The delivery was prompt and very fast. A real plus is the very safe Vepackung the toner for the transport, which are sent twice wrapped in bubble and bubble envelope. The printing result is good and leaves nothing to quirk. Also, the toner differ optically toners from Samsung. When unpacking no pollution or powder residues were present at the delivery point of the opening, as happens sometimes. The price is significantly lower than for the original Samsung toner (50%) and still produces the same performance. I can not say anything about the printable sheets number with the toner, since this is still in use and therefore not yet applied. But nachgreicht when it comes to that. All in all I can only recommend this toner and will also my next order toner for this manufacturer.
