Stories from central americal often seem surreal. How could it be that people so rich can live in such close proximity to those so poor? How could people motivated by such high principals commit such barbaric acts of violence? Insulated and liberal in America we so much want to empatize with the poor when in fact we have so much in common with the rich. I found this book so very compelling in that it provided much empathy for all sides of this conflict. One could not demonize any party. Instead I watched helplessly as the events unfolded and greived each needless loss. I recommend this book for your soul as your heart needs the exercise.
Positive

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.
Positive

I bought 3 sheet sets, I have noticed on the two queen size sheets that the stitching that holds the elastic in has come apart in several places and the elastic is now falling out. I have only washed these sets two times. I am very disappointed in this purchase.

Negative
