TEM GLASS, tempered glass that stands over 150 hits with hammer? legit?

Hello!
Can someone help me list some high quality screen protectors?
I've been using copters screen protectors, on my iphone 4S, but it fell of after a few months when putting it down to my pocket and got some scratches from my keys..

I dont like Otterbox etc since their protection is superior but i simply dont want to carry around a brick in my pocket if u know what i mean.

i simply want a good quality clear screen protector, please help me!

 

Try the Zagg HD protectors, excellent in my opinion.

 

Im using the SGP Glas Tr and LOVE it!

 

I have the SGP Glas.tR on 3 iPhones, mine and 2 of my kids. My son took his off due to changing cases again, and broke his screen a week later. My daughter had a friend drop something on her phone which cracked the screen but protected the actual phone screen and we replaced it with the SPG again. I love mine and use their bumper.
