  I must admit I was very skeptical about all this !!! And above all - There we go, they want the Credit Card details !!!

I don't even know the current exchange rate but proceeded thinking nothing will come of this ....

Within minutes I was sent the RESET CODE along with the RECEIPT FOR PAYMENT !

It worked like a charm !

The FIRST , but definitely not the LAST time I will be using this site !

Thank you !

  I was tearing my hair out trying to get a solution for my Epson R265. Other solutions didn't work and were not compatible with Vista Home Basic. The WIC Reset Utility worked like a charm! In just a few moments - I'm off to buy a waste ink device so I can get a lot more service from my machine.

  Just used the free trial key. Up and running again in minutes. Will definitely be buying the full key when the time comes. Many thanks!
