The reset key worked perfectly. The whole time to purchase a key, download the software, and reset my R2400 was about 5 minutes. Excellent product! Highly Recommended

IT WORKS! IT WORKS! IT WORKS! I tried the free reset key through Epson.com but their servers don\'t work anymore and there\'s soooooooooo many errors. After hours of frustration I paid the $9.99 saying, \"What do I have to lose?\" Just like the other reviews said, you\'ll be all set within 2 minutes.>The reviews have spelling errors (ha ha) so real people are writing them. And to leave this review that I\'m writing, the site made me log in (proving I have an account and truly am a customer that tried it). Worked on my Epson Stylus CX8400.

Is this Adjustment program compatible with the USA Destination? Initial setting was designed for 127 cartridge? Thank you.

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.
