Have the first time for my printer (Brother HL-4150CDN) requires new toner. Not least for cost reasons, I have decided for the product of Hainsberger, and not for the expensive original toner. After a few weeks of usage time I can say that I am more than satisfied. Neither when you insert the toner even when printing, there were difficulties. Everything works wonderfully. I can not tell the difference from the original. Will rely in the future on the products of Hainsberger.
