[Q]: Good quality product. Fits nicely on the iPhone 4s. The screen protector has this weird rainbow effect. But other than that it does what it's supposed to. I would buy a similar product from Tech Armor.

[Q]: Works very well, easy to read even during day or night.
[A]: Good Review


[Q]: Just got my disc set a couple of days ago. It looks awesome! But, as many others have reported, several of these discs don't work. If you try to watch one, it stops in the middle, saying "region error". So I'm returning it. Amazon is great though.

Bad review
