## Customer Reviews

### ⭐⭐⭐⭐⭐ Great compatibility.
*by S***  on June 3, 2025*

Product has worked good for my Epson printer and compatible.

### ⭐⭐⭐⭐⭐ Positive results, amazing price
*by L***E on November 7, 2024*

I purchased this ink maintenance box for my Epson ET-8550 photo printer. I use my printer very often. I started to noticed a decline in the print quality after a year or so of nearly daily usage. I stumbled across this option after doing some research.I was surprised by how easy it was to install and use. The instructions included were very helpful and precise. The printer reacted well it. And it now functions again as if it was new.I found it very considerate that gloves were added to protect my skin from possible exposure.Overall, I’m extremely pleased with this purchase. Since I am typically impartial to using off brands when it comes to my printers in general. But the manufacturers recommended option was drastically out of the budget.

### ⭐ Labeling Inconsistency
*by G***Y on May 1, 2025*

While sorting printer accessories for the ET-8500 and WF-7820 models, the C9345 Ink Maintenance Box had inconsistent branding between the outer box and the insert card, which raised concerns during inventory checks.
