Ques:You are considering whether to buy a product. You look at the reviews. Would the following review decrease or increase the chances of you buying the product? Review title: Not an OEM headset. Product review: This product is not Plantronics. It is a cheap knock-off. This is evident by the lack of manufacturer markings, the packaging and the cheap sound quality. The headset is not loud enough and people I call tell me they cannot hear me. Since it was inexpensive, I'm throwing it away rather try to get my money back. Don't waste your money.

Review title: Great circumnavigation story. Product review: Great read... but frustrating to learn about how ill-prepared the boat and the skipper was for this journey.On the other hand I suspect MANY sailors start out in the same condition. The story itself is fantastic,with lots of excitement and very real descriptions of life around the world.
