The original cartridge is so expensive that only an alternative product in question kam.Die XXL Black for my Samsung CLP320 of Fa. Hainsberger came within 3 days with me. Exchange in the device easily fits in exactly. First sample pressure was a bit pale. Property then times by mail the company. Hainsberger asked for advice. The next day came the reply. (Measure: Shake toner cartridge and a few pages in I'd also full pressure itself can get it). The part will now work properly. No difference from the original toner. Can I really recommend it.
