Q: 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.

A: Negative

Q: I bought this charger thinking that it would be compatible with my late 2005 iBook G4. The description page has nothing stating that it is not for ibook G4 but only for Powerbook G4 and ibook G3. Also, after only about 3 weeks of use the charger died completely. This is by far the worst charger I have ever had. Pros: quick ship Cons: incorrect description, lack of durability

A: Negative

Q: This book is amazing. I read it when I was a child and couldn't put it down. It has amazing adventure and suspense, without the horrible violence. Several months ago, something reminded me of the book and I had to hunt it down. I had forgotten the title and the author(it had been 15 years since I read it). I finally was able to locate it. I was thrilled. I bought it and read it in just a couple of hours. It is a book I recommend for both children and adults.

A:
Positive
