Great color saturation
I have only used this a couple of times and was concerned about the dull colors when it printed out. But the listing warns you about that so I went ahead and pressed it. Perfect! Bold colors and high quality images. Plus, filling my printer only took a little over half the bottles. Great value for the money and I will definitely be ordering again.

Superior Customer Service; 100% prefect and functional, BUT...
Number of Items: 2
This product fits perfectly, after all it's just a simple piece replacement. The big deal is the counter reset, and this is where Customer Service outstands. People complaints about the difficulty of following the reset instructions, and with reason, as they are lengthy. But that is the printer you have, that is Epson's product. You either send the printer to them and pay the premium fee, or do it yourself, but you have to play their game. This is not Seller's fault; on the contrary, Seller put all their effort to include each and every steps you need to fix the problem, no matter what printer model you have. They included most, If not all, printer models you may have. They provided super detailed instructions to ensure your success; keys where needed, no keys where not needed, printer drivers location to download and ensure the resetter will work and, best of all, support if you need it. You have to contact them through Amazon asking for the user's manual (instructions; yes, the lengthy ones), the reset program and the reset keys if applicable (this depends on you printer model; some need the reset keys, some do not). And this is where you get concerned: When are they going to answer, now that my printer is locked? You think (I did): it is weekend, they will probably answer Monday or maybe Tuesday (after all, that already have the money, why care?). Well, I was absolutely wrong, they answered during the weekend with all necessary to have the printer back, up and running; Thank You. Some tips: 1. There is nothing wrong with the software (if got from a reputable source, and they for sure are), so get it without concerns. 2. Get the printer driver as advised; it is quite probable that the software will not work if you don't install the correct driver; don't forget to restart the computer after the driver installation. 3. Make sure your printer is set up with the USB connection Enabled (mine was disabled and that caused a headache: ET-4800). 4. When the resetter instructions call for Initialize the Counters, don't do it, not yet; select Check instead, just above Initialize. If you cannot read (Check) the counters, you will not be able to Initialize them: fix the connection problem first (make sure you installed the printer driver and RESTART the computer, make sure you enabled the USB connection in the printer, and make sure the usb cable is correctly connected). It's not Seller's fault to make long and complicated instructions, that is actually their effort to make sure you have all you need to succeed. Buy with confidence, this works: if you cannot make it work, you may find someone you trust to help you out (your kids or grandkids know a lot for sure), or just let Seller know, they are willing to help you out. Best regards.
