I bought some of these in 2007 and still use 4 years later at the local farmer's market. The first one is cracked from wear but no fault to them. Great product for a really good price.
Good Review

This book was written in the 70's by a man who knows his stuff, which is a rare find nowadays. The problem with it is that he relies too much on anecdotal stories and anecdotical sources to support his hypothesis. It feels like reading someone's blog, not science. Also, some of the anecdotes don't make any sense unless you can explain away how they happened.
Good Review

The book is a very good read.......until the part that has nothing to do with his life before he was in prison... Don't get me wrong I support anyone doing hard drugs BUT having more than one or two pages dedicated entirely to how great you are and what you're into will have most people throwing this item right back where they bought it....

Bad review
