Review on 🖨️ High-Yield E-Z Ink (TM) Compatible Toner Cartridge Replacement for Brother TN580 TN650 TN550 TN620 - Compatible with HL-5370DW HL-5340D DCP-8060 DCP-8065DN HL-5240 HL-5250DN MFC-8660DN - Black, 2 Pack by Jasmin Rojas

I bought these cartridges for my printer because of the price and compatibility. I put one in my printer and got errors including a blinking light on the toner gauge and also a red light on the status light. I've been waiting to use it because I don't print much and I might be able to work with the old cartridge for a while. I've waited too long to check them out, so Revain won't take them back. Now I'm stuck. After a while my toner cartridge stopped working so I put the EZ Ink toner back in. When I turned on the device, I was greeted with a series of loud pops, followed by flashing LEDs. I put the Brother cartridge back in and there was a loud popping noise and flashing lights. Apparently the cartridge damaged my printer beyond repair. They did not reply to my email asking for compensation. DO NOT BUY!
