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.

Ex Output:
Good Review

I've been an admirer of Steve McQueen for a long time. I first saw The Sand Pebbles as part of the series on TV when it was broadcast in 1974. As soon as I knew he did not have anything to do with making this film or writing it, so much as directing and producing, it became all about me.

Ex Output:
Bad review

Ex Input:
The first time that anyone attempted to watch this they had to skip the entire movie and then it worked perfectly. I like this film. Not sure if my machine was in error or what, but a disappointment. Still for $5.99, its great deal all right...

Ex Output:
Good Review
