[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 am a complete Sudoku addict and am very disappointed with this book. The only reason I bought it was because I was desperate for more puzzles and it was the only one available at the store I was in. First of all, it costs $4.99 which to me, is way too much money when you can get a Kappa book for $1.99 which has better puzzles. Another thing that bugs me about this book is that some of the answer keys in the back don't match the corresponding puzzles. When I get to the difficult/Very Challenging ones in the back, sometimes I need a little help! But unfortunately, this book has quite a few errors in the answer section so when I've hit a dead end, it's over.I would recommend Kappa books from your local supermarket. This simply costs too much money for not mush quality.
[A]: Negative


[Q]: I love Greek History and mythology. When I heard a mini-series of the Odyssey was being created I was anxious for two reasons; I was dying to see it and was terrified of how badly it was going to be butchered. This was a delightful surprise.To my amazement the writers took some minor literary license with the story but all in all it worked. What is even better...it was a lot of fun to watch. I would recommend that anyone thinking about buying this do so... but also buy the book. Turn your brain off watch the movie, engage the brain again and read the original story. Either way you are promised a good time.

Positive
