[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 did enjoy reading the book. The story was interesting, even if it ended a little too soon for my liking.
[EX A]: Good Review

[EX Q]: The first four books in this series were great. It is nice that the author decided not to continue and keep the story alive for a possible third book. I hope she ends that series. This book was rather disappointing though. I think it was a little bit rushed. In fact, there really weren't any surprises or surprises. Everything made sense at close of second book, but by mid-through it, everything started tying together. Nothing much happened like you would expect. Very disappointing.
[EX A]:
Good Review
