[EX 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.
[EX A]: Good Review

[EX Q]: This movie was just plain awful. I found it boring and the acting not very good, in my opinion. Do not waste your time on this one.
[EX A]: Bad review

[EX Q]: If you are thinking about switching your old mouse to this wireless one, DON'T. I have a wired Logitech mouse, and the new cordless is very inconsistent on its signal quality. It will either freeze every 10-30 seconds, or just stop doing anything, so what good is it? After 2 months of buying this, I've decided it's better to use my older one than this.
[EX A]:
