  I have reset the waste ink in my epson R230 printer. Worked fine
  Michael Reed 2012-04-05 22:26:45  
  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.

  Great service, with good online instructions, for a nubee, this is the first time I have had to do something like this with my printer, will recommend you to my photo club.

  Thanks for your prompt service, I ordered a reset key for a Mac os 10.5 The new version of the iWic for Mac worked great. We are back in business. Thanks Clive Lewis
