input:  Now, answer this question: Title: Warning: Not for beginners! Review: This book assumes that you already know the basic mechanics of BJJ and therefore, it jumps right into the techniques. This books could be used more as a reference to someone who has BEEN learning BJJ for sometime. This book is definitely not for the beginner. The explainations are very vague. A beginner would most likely execute the techniques improperly if not supplementing this book with an actual BJJ course. I would not recommend this for a beginner nor an advanced student.

input:  Now, answer this question: Title: Does not fit original OEM pump or AC Delco replacement pump Review: Completely useless for its intended purpose. The vendor obviously has a major quality control issue. The internal diameter of the wrench was to small to fit over the old or new water pump, and the tab spacing didn't match. After wasting a lot of time figuring out what was wrong. I purchased an Autocraft brand at the local parts store, and it worked in 10 seconds. Is this product review negative?
