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.

I always bought the key and it arrived correctly, but unfortunately in my last 3 purchases, the key did not arrive. I already sent an email to support with the order number with the problem, they told me that everything was resolved, but nothing was resolved, and I still don't have the key. very bad and slow customer support, it took almost 2 days for useless response.

I was very happy with the ease of ordering & installing the WIC Reset Utility Key. My printer is up and running once again after I replaced the waste toner box. THANK YOU
