[Q]: this guy had his wife write it. He says he's going to teach her how to use a computer. He's not. And he doesn't even mention that.
[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]: I bought this book because the title sounded familiar. So far I've only had a few problems with it. I'll have to see how many more glitches there are. The one problem that makes me, not a little bit uncomfortable, is in chapters 4 and 5, on page 14, a whole bunch of numbers are cut off, such as.433=.0457... On all other pages, however, except for 2 or 3, they come back on. Not sure why.
[A]:
Good Review
