[EX Q]: I bought a pair of these at first and one has stopped working just after the return day. They sound great while they work but if you want headphones that will last you buy something else. Also tried to get in touch with customer service twice for this issue, only got an answering machine most times. Not worth trying since they were never able to send me another headset to make it right. I'm done returning them. Amazon took care of them quickly so I give them five stars.
[EX A]: Bad review

[EX Q]: Nice book, the only thing I didn't like about it was that each time a new topic came up throughout the first 30 pages or so we learned more than needed and it wasn't very interesting. It also gets a little boring around page 100 but does pick up. If you think you're going to take pictures of every bird in a local neighborhood, buy several books on your own first, this book is an okay one for that.
[EX A]: Good Review

[EX Q]: I have been buying coffee at Starbucks since 2004. My friend gave me a French press, so when he threw out his new one, I tried his press and hated it. So I've decided to order my own. This is the worst product in history. No matter how little coffee you put into it, it seems to be too strong. You can still smell that horrible taste with every sip...disgusting. Waste of money. :-(
