Review on 🖨️ High Yield v4ink Compatible Toner Cartridge for Brother TN450 TN420 - Twin Pack by Edward Noble

Terrible. I've only used it for one day and I'm not sure if I should keep using it. I'm afraid it will ruin my printer. The print is a bit fuzzy, the pages have black borders, and sometimes there are actually wet ink blots on the paper. I will never order these cartridges again. Unfortunately the brand I ordered in the past is no longer in stock. 1/7/17 The seller responded to my negative feedback and offered to replace the cartridge. I appreciate your efforts. The new cartridge was an improvement. However, my printer has never been the same since I used the first horrible cartridge. There is a black shadow on the left edge of all sheets. I had hoped it would eventually pass. I wonder if there is a way to clean the printer.
