Beware of the size of this book!If you are expecting to receive a regular size art book, you will be extremely disappointed. The book measures 7.5 x 9 inch and is thinner than my pinky finger.However, if you are just interested in the content, there is a lot to look at and to read.

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.
Negative

Waste Of Time & Money... I found that if you want to win big, just put the money into a savings account & watch your money grow! Pay YOURSELF not this author.
