Input: Consider Input: I got this item within a few days of my purchase. It is exactly what I wanted -- I look a whole size smaller, instantly. I tried on the Squeem in a boutique and fell in love, but they were asking almost $200 for it! I highly recommend this item and the seller.

Input: Consider Input: This is the best true-crime book ever written, imho. I actually read this in high school in the 1970s and did a book report on it for one of my history classes (got an "A"). It seemed like none of the other kids had ever heard of Manson or his "family". I read this book so many times the cover was in pieces. If you want to read a scary, gory, and TRUE book that will scare you, don't bother with any of the other books out there. Read this one. It will give you chills to realize how much control one man can have over other people. Of course, since the time of the Tate/LaBianca murders, we have been desensitized because of the Jim Jones, David Koresh, and other cults... But Manson's directives started them all. Very well written.
Output: Positive
