Expensive but properly without any problems. Since my MFP - device is still under warranty, only these parts in use. Moreover skeptical because alternatives here at Amazon already considerable difficulties in retrospect made (soiling etc.). This I had not and give rather more of in order not to have to buy a new device. The printer manufacturer to obtain the merit now about these products - is well unfortunately well known, but in the apple I bite before I learned the hard way (with OKI - have already experienced printer itself!) Pay.
