Toner is offered at an unbeatable price, just as unbeatable unusable is the product! The printing result of black spots, stripes and edges defaced so that you can refer to it only as useless. After the complaint was made, although a quick replacement, but what had the same negative characteristics! The printer and the printer location were beaten toner (carcinogenic!) Contaminated. To this was then the fact that the sender claimed that the returned cartridge supplied (not out of his range) was not !!! - And a reminder of the purchase price fluttered into the house. Conclusion: I can only warn everyone to buy toner cartridges with ink pool.
