Review on V4INK 4PK Compatible 410A Toner Cartridge Set for HP Color Pro M452 and MFP M477 Series Printers by Delos Rodeo

The cartridges worked great for about 9 months then the red started to fade then blue then yellow. Everything showed @ 75% on my printer. Black was ok then started fading. It went down to about 20%, so that's what I was expecting. I would give them 2-3 stars if it wasn't for the phenomenal customer service. I contacted them and they sent me the complete set for free. Unsurpassed. Earn 5 stars for customer service! The new ones have been working great for a week now. I will update the post if anything changes.
