What is the best brand for the iphone 5 privacy screen protector?

I just bought the one from Zagg InvisibleShield and it's horrible. I want one that will protect from all angles and won't dim the light on my phone too much while I'm looking at it front view, if that exists.

All screen protectors are the same. It is just a piece of plastic that is sticky on one side. But there are companies who will convince you you need to spend $20+ on a screen protector that is really worth $1-2. I recommend this: http://www.ibrandaccessories.com
They sell it for the correct price and they are very nice.
