Product itself- 5 Stars. Customer service - 5 stars. Giving 4 stars because the installation tray needs some improvement. Firstly I’d like to say I’m overall very happy with the quality of the iPhone screen protector! I noticed the screen clarity and ease on the eyes immediately and the anti-smudge/fingerprint is really good! The only thing I think can be improved is the installation tray. I have used some that close like a book, and you pull the plastic off of the glass while the “book” is closed, so there’s no dust or bubbles. With occushield I had issues with dust and bubbles and had to lift off the corners and remove with tape. There was some dust trapped under but I gave up and left it there. That being said, in the first week of use I already have some cracks in the corners and I didn't drop my phone, so I don't know how that happened. However, I emailed customer service asking for a discount to buy a new one, but they replaced it for me free of charge. I really appreciate that and the wonderful service. Thanks!
