If you're looking for a water softener to reduce mineral build up in your water, this is the product you want. I have used RO systems before, and there isn't a whole lot difference between them.
Good Review

This is my first book review and I am quite surprised at how disappointed others were with this book. I've read many books on this subject in the past 20 years, including works by Michael Collins, Peter Kuznick (Who's Afraid of Red Riding Hood?) and even Andrew Wakefield. A lot has changed with respect to vaccines and our vaccination status today.
Bad review

The book itself isn't bad, but I won't buy anything from this publisher again. They shipped the first copy to me with many holes around the spine, and they sent a second one, which was still in bad condition after all this. This is just poor quality control. Amazon has always been good about this, so what you should do at least if it's going to be shipped, get it checked out by another customer who says it works fine.
