Positives: Fast delivery (Amazon content) and low price. Negative: Black was after max. 400 pages empty again Yellow felt after 200 pages Red exchanged in a day 2 Toner ---- printed pages 5 and was yet to be replaced again. Red (Magenta) was also at 1 Toner plastic packaging unsealed (possibly empty toner?!) On the same day yellow toner also exchanged - Display empty, although not printed. Black should be also exchanged lt ad -. Taken out and used the same toner again - for the time being can be printed on. General suspicion: Toner was not filled completely or CHIP not exchanged or used defective chips. Conclusion :::::::: Who buys cheap, buys expensive. Steer clear of this Klump !!
