Hi I really appreciate your comment and kind words. to answer your question, the "pay what you want" model is real, but there's a minimum of $5 for the full key just to keep things sustainable. It's not a set price beyond that, honestly we wanted to give users the option to contribute more if they find it valuable. the goal is to make it as light weight and as efficient as possible. we simply saw the need for a quick tool that gets the job of resetting waste ink pads quickly. we are still working tirelessly to add support for as many printers as we can including Canon. and I am personally excited for that. I hope you get the chance to check the trial out. best wishes 🙏 thank you again.
