My original toner was suddenly empty. Then came the difficult deliberation expensive original or an alternative? In the beginning I had regarding the low price compared to the original but my concerns. Due to many good reviews I decided for Hainsberger. The delivery arrived quickly and was good and clean packed in air-cushioned cardboard freshly sealed without toner outside the cartridge. I can not tell the difference visually to the original. The cartridge fitted immediately on the mm and was recognized by my Samsung SCX-3405 immediately and the printer software displays the level correctly. Quality of prints is impeccable and the printer does not realize that it is not a genuine cartridge. Strong buy recommendation for the Hainsberger toner.
