After numerous warnings of low or nachbefüllten toner cartridges I have wg. the many positive reviews but tried the Hainsberger cartridge. The price differences are simply too great (70 EUR Samsung Original for 1500 pages vs. 26 EUR Hainsberger for 2500 pages. So for a fifth of the cost of printing / page!). And it was a great success. The replacement of the cartridge is simple, even though I have two left hands. A small "shock" I was able to solve quickly the super cute Hotline - the cartridge did not fit because I had forgotten to remove a plastic protective cap front. Immediately after inserting the printer recognizes (my model is the Samsung SCX 3200), the cartridge automatically and printed on. Who else paid more money here is really your own fault.
