[EX Q]: The sound is good enough and the Bluetooth connected great but after a few months they stopped working. I contacted LG for a replacement which was quick to get here with no hassle. So far so good, however, their claim that their product contains "durable materials" has me doubting my purchase. I've worn them every weekend day while work at an office since December 2013 (maybe 2 hours a day, if that) and today is finally the day when one side died.
[EX A]: Bad review

[EX Q]: I was very excited to find out this book had been made into a film and I'm not too keen on the book. The movie adaptation has me worried. As you can probably tell it doesn't quite measure up to the book, some of my favorite elements were changed so as not to take away from it's story such is all love stories have to do. It's still a cute movie, but not really what I expected. Worth the watch though, just don't expect a classic story.
[EX A]: Good Review

[EX Q]: The title of my review pretty much sums it up... I just recently got this book and there were several pages missing from it. It was extremely obvious that someone had run the books through an OCR software program before sending them to a publisher. Some areas in this edition were more than readable, other parts not so much. I've ordered many textbooks online for less money and have gotten better quality with them.
[EX A]:
Bad review
