It's really easy to use and has saved me tons of money over buying new printers. I've reset my current printers several times and have used them for over 5 years thanks to these reset keys.

thank you for the free trial!! I think the printer companies should give low income customers the reset key free!! It took me a few tries to get this to work, but was successful. You saved my day!!

I was skeptical, but I paid for a key and the WIC Reset Utility program worked PERFECTLY on my Epson ET-2400. Thank you!

I was amazed how easy that was. I was in doubt that this simple download would work... with my heart racing! I entered the key,and there it was, all fixed. 2manuals, I must say, what you said it would do, it did, and I\'m so relieved and happy, and can work again. The success of this has made me want to write a review on your product right away. Thank you so much Robert Dorsey President/CEO Cabin Watch Fine Time Wear
