  Hi, I'm particularly satisfied of the Wic Reset Utility I just used for the 3rd time (2020, 2022 and now) for my Epson WP635 Printer. I had felt pads left from the last time, easily replaced them thanks to the excellent instructions found on octoink's site, then bought a new key and re-intitialized my printer in minutes. My printer is now renewed for 2 years! Very very satisfied. Many thanks. MF, France

  I was tearing my hair out trying to get a solution for my Epson R265. Other solutions didn't work and were not compatible with Vista Home Basic. The WIC Reset Utility worked like a charm! In just a few moments - I'm off to buy a waste ink device so I can get a lot more service from my machine.

  Very helpful - thank you. I was stuck as I use a Mac and your Mac software saved the day. I used the trial key this time to be sure it worked, but will be happy to purchase one when I need it next.

  Reset key itself WORKS, hurrah! 5 stars. BUT . . . it was a struggle to get the download. Our MacBook which is a few years old does not allow the download to be installed because Apple blocks "unrecognized developers." That should be taken care of or a warning should be placed on all promotional materials related to WIC RESET KEY. I was able to get the download onto my old Apple desktop which has not had operating system updates. That's how I finally purchased the reset key. Please tell me why the whole business of the reset key, after replacing the ink pads, is not an example of contrived malicious obsolescence? I was tied up for hours, cursing the Epson company, and a breath away from buying a new printer, adding plastic waste into our environment. I liken my experience to changing a car's oil filter and then needing a code to start the car again.
