  OK Im here because Youtube directed me here to fix my Epson ET-2803 printer! I've downloaded your APP and tried to use it! ...There are a number of problems!!! ...First off, couldn't you find any smaller text!!?? Trying to read and follow your directs is near impossible! Next up, your directions aren't very clear! You direct me to turn on my printer then to turn it off. And as I try to move forward I click on your direction and NOTHING happens, until the command times out. BUT IF I turn off my printer again (un-directed by you) the command tried to go through. UNTIL I get more directions to turn on my printer and not turn it off again. I've seen a line at the bottom of the screen there a line of text floats through saying that the computer has been reset per the Youtube site I'm supposed to get a congratulations of a successful at the finish, I never get that, because my last command (theoretically) never goes through, again just sitting there until it times out again. IF your really trying to "help" people PLEASE fix you site! Because nothing seems to work correctly, I'm hesitant to buy any keys from you. ...Sincerly, Mark L

  I have three Epson R290 Printers and this is the second one i have had to reset. Your system is the best by far and for $9.99 you can't say no. Yes i was able to purchase the waste pads from a place for only $5.00 so now I should be able to keep on printing. Thanks again guys well done.

  Fantastic product key that saved me from rushing out and buying a new printer, allowing me to wait for the parts to arrive in order to keep on working! The very best value for money and thank you so much for the service!

  Before unzipping the downloaded file, please disable the antivirus software. The tool works great for me. The Canon G1010 is a great inkjet, and this tool make it live again.
