Review on 🖨️ VAKER Remanufactured Inkjet Printer Ink Cartridge Tray Replacement for HP 63 63XL Combo Pack - OfficeJet 3830, 5255, 5258, 5200, 4650, 4655, Envy 4520, 4510, DeskJet 3631, 3639 Printer (Black & Tri-Color) by Troy Hamilton

At first I was very happy with my order. Everything was working fine until a day ago. Then my color cartridge didn't work. The computer kept telling me it needed to be reinstalled. I've done this several times but it still didn't work. The ink level in the color cartridge showed zero ink, but the black cartridge was 3/4 full, which the color cartridge should show. Something went wrong with the new chip they put in the remanufactured cartridges. I had to go to Walmart and buy a new one as my return period was a day past. I tried them again but was disappointed with this first purchase. .UPDATE #2.After my first upgrade the company contacted me and offered a refund or replacement for my color cartridge which failed 1/3 of the way. They offered me this even after the return time had expired. How often do companies do this? I went with a replacement because I wanted to give them the benefit of the doubt and also because the black cartridge works great. I believe the first color was an anomaly. I even ordered another set from them. If these cartridges are as good as their customer service and integrity (which I believe they are), they might add me to their list of loyal customers.
