  Thank you for helping me reset my printer and for the free trial key. You saved my day.

  All I can say is thank you so much for saving my printer. I changed the ink pads ( very simple task ) and used the Epson Reset. My printer still did not work and I was devastated. I spent MANY hours online researching the problem ( Epson was absoutely no help at all ) and finally came across your product. I used your program to reset the ink pad counter and it reset the counter as advertised. After I restarted the printer It would not do anything. I uninstalled all of the Epson software and reinstalled with the original disk that came with the printer. AWESOME a new printer!!! I can not tell you how much i appreciate your product! I thought I was buying one of the best printers on the market at that time and I am really TICKED off at Epson for building in an unnessisary self destruct. I had purchased every upgrade for my printer Epson offered and was determined to get it working again and you did that for me. THANK YOU !!!!

  I have three Epson R290 Printers and this is the second one i have had to reset. Your system is the best by far and for $9.99 you can't say no. Yes i was able to purchase the waste pads from a place for only $5.00 so now I should be able to keep on printing. Thanks again guys well done.
