I used the product after my original screen protector got scratched and had to be removed. Diamond Defense was easy to apply. I took my time to get full coverage. It didn't seem to be adding anything at first but when I was finished and I did the final buffing, there was a beautiful clear coating!
Such a great product. It was easy to use and had enough of the liquid to do my phone, my boyfriend’s phone, and the back cameras on each of our phones
