As a student of jiujitsu i understood alot of the moves but i found that without previous knowledge these pictures and instructions were difficult to understand. I feel there is alot of good information but not worth buying.

Ex Output:
Negative


Ex Input:
Good quality overall. The braket for the stem didn't fit my application, so I improvised, and mounted it behind the seat over the rear fender and low. Holds stuff.

Positive

Hawthorne's dull prose really gets to you after a while. The book is filled with antiquated language, and is basically an account of a Puritan woman who suffers because of her adultery. I was forced to read this book for my English class, and it was a terrible waste of time. Hawthorne hits you in the face with run on sentences that take up the entire page. I do have one good thing to say about this book however, for all you insomniacs out there, read it! It induces sleep in minutes! ZzZzZzZzZzZz.....

Ex Output:

Negative
