[EX Q]: If you're looking for a water softener to reduce mineral build up in your water, this is the product you want. I have used RO systems before, and there isn't a whole lot difference between them.
[EX A]: Good Review

[EX Q]: Not only do this things look great and sound great, the bass is amazing!!! they are very comfortable to wear, but after about 30 days I got a short in them where they connect into your iphone or ipod. Don't waste you money on these
[EX A]: Bad review

[EX Q]: This book was the absolute worst. I gave up on it about 15% in because I could not believe how ridiculous some of these situations were. It seems everyone is a liar or crazy and no one should ever be trusted. One thing that bugs me more than anything else though is there were so many characters with really odd names. Is this to show us people have changed throughout history? Because by all accounts if you change something even slightly over time you'll always sound like an English idiot.
[EX A]:
Bad review
