I have used several supershieldz products. And I've never dealt with them. But somehow the dust got between the protective plastic and the screen protector. At first I thought I was gathering dust when I put them on the screen. The second time I was upset. I took the third and last one, held it up to the light and saw the dust between the two layers. I tried my best to clean it. Then I was able to put it on with only 3 small dust pockets. Not at all happy about it. Before attempting to create your device. Look for dust or dirt between the protective plastic and the screen protector. If so, send them back. In general. I love the matte finish. This makes the drawing look more natural. I only wish their quality control staff could do a better job.
