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: This book was a complete waste of time for me! I thought it would be good, but what happened? When you consider that it's just like every other romance novel, the only reason why you'd still want to bother reading this is if you're into all these things. But I'm pretty sure you'll find better things in your fantasy novels, and those will leave you much happier.

A:
Bad review
