I have been a BodyGuardz user for many years now and have always consider this an excellent product. Have everyone in my family also using this on their phones.
I originally bought the screen cover when I bought my new iPhone and they did tell me it had a lifetime warranty. I dropped my phone and the screen cover protected my phone exactly as expected! And then when the cover was cracked their warranty of their product performed as well exactly as expected. I could not be happier!!
