So far, no differences determine the genuine toner

The Toner Cartridge I have used in my HL-2130, after the original first equipment was used up, and so far I have found no differences to the original toner. In the first pages was initially a black stripe on the right side, which is but left after a few print and twice pushing the coronary cleaner - I may have had in sharing the slider is not all the way out to the left stop. However, I have no 1000 pages printed thus: if the advertised range is really to achieve, so I can not say yet.
Just a pity that no empty envelope for the old cartridge came with, the manufacturer builds apparently rather new plastic containers as the old to refill.
Overall, in my view, a recommended replacement toner with which the side prices are back to the earlier usual range of laser printers.
