TASK DEFINITION: Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
PROBLEM: I've noticed very little degrading of the sound, if at all, and this is rare in most extensions. The cord is thicker than usual for both the positive and negative polarities - a separate wire for each - and I'm quite pleased with this, will perhaps get another because of its thickness. I now have great headphone sound within a twenty-foot range - just what I was looking for. Even if you don't need 15-feet of cord, I would recommend this over the shorter 10 foot cords where the wiring is about half as thick and not likely to hold up over time...I subject all my electronics to heavy use. Plus, the best extensions for Grado headphones go for $40, and I'm quite satisfied saving over $30 by having this one.

SOLUTION: Positive

PROBLEM: I personally enjoyed ever word of this particular work. Many other reviewers have gone into the plot, etc. so I will not do so here to any depth. This is one of those works of SiFi that will appeal to certain taste, while others may find it not to their liking. There is a great deal of politics (almost Pre WWI European) involved in the story line. As the story covers (all books included) over one thousand years, there are many, many characters to track and keep track of. This is indeed a series of short stories, all linked. I personally enjoy this sort of thing but can see where some might not. That being said, it, the book, can certainly be regarded as a classic in this particular genre and certainly should be read by any student of such. You certainly cannot fault the author's story telling ability and imagination. I enjoyed this one a lot and do highly recommend it.

SOLUTION: Positive

PROBLEM: Unfortunately, it's two left feet on this occasion. I bought the book as I am a big fan of both Holmes and Dracula stories, but despite the sometimes colorful characters, it was a tedious read.

SOLUTION:
Negative
