Review on V4INK 5PK Remanufactured Toner Cartridge for HP 305X/305A - High Yield - HP Pro 400 MFP M475/M451/M375 Printer by Danierl Temple

The toner and print quality of this product is good. My problem is that I'm starting to get strokes of color on the edges, which first spread across the entire page. This is at 60% waste toner. When I print a page, most of the time the copy is blank. Several copies or pages are dirty. As an update, V4ink contacted me to help me solve my problem. They suggested I shake the toner cartridge which improved the print quality. They were very generous in sending me replacement cartridges so I now have a quality print. V4INK's customer service gets 5 stars. I'll see how well the new cartridges perform over time.
