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: I enjoyed this book-- it was much better than the standard "chick lit" titles. It was a lightweight story, easy to read, and the Roman food, cooking, markets and people were fun. Didn't mind the creative cursing-- how very true to "Roman young stud" it was! Maybe the Laura character was a bit underdeveloped, but I much prefered to read about Bruno.I liked this book SO MUCH more than "Cooking for Mr. Latte" - it was a fun read.

A: Positive
****
Q: According to Leach, corporations, academia and government have all worked to disengage Americans from their places of nurture so that Americans and indeed the whole world will travel, consume, and search continually for new things and experiences to buy. Upon reflection, I ask myself how Professor Leach convinced me that one-size-fits-all containers (for trains and trucks) supports his thesis.

A:
Positive
