It destroyed the printer I was using with non-genuine toner from another company without any issues.

The rating only applies to the price, which is below 5 euros. Compared to the original toners that cost as much as two new printers, it is definitely the best solution.

I disregard the references to 1,000 printed pages, as the toner doesn't even last for 100 pages.

What I still don't know is the fact that the printer gets stuck and doesn't print all the pages unless you cancel and reprint the documents or open and close it. But even this, if it is due to the ink, is expected considering the cost.
