Initially, I was very pleased with these screen protectors. The application process was made easy by using the plastic guide, and the cleaning materials ensured there was no dust. The application was perfect with no bubbles or raised edge.
However, it has only been a week and there are already two visible cracks in the glass of the screen protector. I have not dropped my phone, sit with it in my back pocket, nor in any way caused an impact that would cause the screen protector to crack. Unfortunately, I will be returning the screen protectors and buying a different brand. Yes, there are two spare that come with the pack, but I do not have the confidence that those too will not break under little stress either.
