Excellent , i was a bit dubious about buying a key in case it didn't work or that it could be a con , but im very very happy i did get this utility & purchased a key . I used this utility to reset my Epson SX-110 which was giving me the message " ink pads had reached the end of their life " & needed service i ain't paying �49.99 just to have a sponge replaced , so a big THANK YOU for the tool & I WILL TELL MY FRIENDS WHO HAVE PRINTERS ALL ABOUT YOU .
