  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.

  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 :-)
