I've had this from November 2019 to the present day (August 11, 2020) and haven't had any issues with the dull feeling going away even though I draw a lot on my iPad. I have two small scratches in the corner of the screen that aren't visible when I turn the iPad off - not bad for almost a year of constant painting. Edit: now, January 25, 2021. With a few sketches, it still feels the same. . Highly recommended!
