My 2 cents for Zagg. I had experience with their older products back in the iPhone 4 era. They're overpriced for nothing. Better alternative everywhere. They would get damage very easily.

Now, in 2016, I don't know how their tempered glass is. But at work, I deployed tons of screen protector from this brand

I can say, they are really well done for the price. The only downside is it doesn't cover all the screen. The protector leaves borders are the screen in case you put a case.

Personally, I stopped using shield since Nexus 4. With Gorrila Glass, you are safe. Though, I am not doing any construction work ... but I got kids, and they tested the screen many times.

Hope that helps.

I got the JETech one on amazon. No Halo, you can see here

I have the jetech tempered glass one. It does have a slight halo effect, but I truly don't notice it unless the screens off and/or I'm really looking for it. It may bother you if your a stickler, but I agree with the thousands of reviewers who gave it a thumbs up.
