Q: This was my first purchase of a vibrator and was very disappointed. It was shipped very discreetly from Amazon directly, but it didn't work. I put in fresh batteries and it wouldn't turn on. I even tested the batteries, they were good, but this rabbit wasn't. Unfortunately, Amazon doesn't take returns on this type of personal product. I simple won't buy anything made by California Exotics again. I'll try one of the other brands next time.

A: Negative
****
Q: Author doesn't believe in any biological interventions and feels you should just accept you kid's disability and get on with it. Needs to spell check his work also.

A: Negative
****
Q: Overall ok. Not much going on here. A lot of internal dialogue, nothing like the movie. I prefer the movie to the book.
