  thank you for the free trial!! I think the printer companies should give low income customers the reset key free!! It took me a few tries to get this to work, but was successful. You saved my day!!

  Wow! Epson wanted standard charge of £118.80 to replace my ink pads. So I bought a set for about a fiver (on eBay). But then Epson would not provide a reset code - they still wanted £118. 80. Then I came across this service and hey presto they provided a code for under a tenner. They deserve all the business they can get. Well done. From Ken Fuller
