  I received my reset key for the printer and after entering it, printer was successfully reset. Thanks, Worked great.

  brilliant - absolutely brilliant. Thank you. Thought I would have to trash my printer and the unused ink cartridges. Only hiccup was needing to disable my security protection to install this wonderful product. Used it as a trial - which proved it worked - then bought the key to finish the job. I am wrapped as you have saved me hundreds of dollars as there is nothing wrong with the quality of the printing. Cheers, Alan.

  I just bought five keys and used the first one. It magically worked. Epson XP-422 is back to life. I also took advantage to clean the waste box. This is also important :-)

  XP322 ran out of copies and froze up. I read up that it was an Epson device to sell more printers but discovered your site just before treating it to a display of bad temper. The 20% of extra time will make the replacement question easier and i can use my stock of ink up on this 4 year old printer. I may even use your services to zero life the counter as it isn't a bad device really. Thank you so much.

  I am so sorry for the bad review 8 gave. I jumped on too soon. I totally retract all of my statements. The key worked perfect. It was totally worth it. I will use this service again when needed. Again I am really, really sorry.

  Thank You. I had just bought a new printer and Epson asked to update the firmware...unfortunately in the middle of the update my power shut off. I thought for sure I had deep sixed my brand new device. Even on the Epson website I could not find a manual firmware recover for my printer and OS version...others printers yes, but not this one. I found you website and thought I'd give it a try. Horray, My printer is back working again. While I am not happy to have to pay someone else for something that Epson should have given for free, your price was with-in reason and your software was easy to use.
