The book was informative and very easy reading as all the other books written by this author. If you are considering starting your own business, go ahead with these books,or any of his others they will give good information. Mark

Ex Input:
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 Output:
Bad review


Ex Input:
It doesn't work, just gives audio. Plugging into VGA converter causes screen on older computer monitor to come up. Not worth returning. Too much hassle. I'll buy one from local store if this fails again. Lesson learned for me. :(
