Q: This book is short with only 26 pages. If your looking for a very basic overview then this would be fine but i think people wanting to understand economics will most likely get just as much from reading my blog.

A: Bad review

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.

A: Bad review

Q: As other reviewers mentioned, only sound worked. This is definitely not worth $10 let alone $20. Do Not Buy, even though they don't say it. I'm very disappointed... I've thrown away shipping cartons, etc.

A:
Bad review
