Decided it's time to try these cheap toners. Shipping was fast. When toner cartridge came in it was well packed, however when I installed it in my printer (Brother 2270DW), the toner light kept blinking and it was showing to replace the cartridge. So the printer did not want to print at all. Its like there was no cartridge installed. I googled a bit and I found this toner reset procedure for the printer. After that it was good to go. Its been a few days since it started working and so far so good. I like it since its cheaper.
