Hi, This is the second time I have reset my waste ink counter in about 18 months. Disappointed that the key I ordered (OS X Mac version) came to me as an exe. Luckily I had anticipated this and had a PC at the ready. That of course worked like a charm. Thanks anyway.

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

Many thanks. Your reset application allowed me to reset my Epson XP-830 to let me get a few more prints while I wait for my new printer to arrive. Great!!!

I just bought a reset key, everything works perfectly on a Epson XP 520. Just one thing, one key for several reset will be better. Thank you for your job.

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.
