Input: Consider Input: 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.

Output: Negative


Input: Consider Input: All of the good things said about "Helter Skelter" is true of the Kindle edition. What's more the Kindle edition has hyperlinked footnotes that actually work and take you instantly to Bugliosi's notes. But the trade-off is that with the Kindle edition THERE ARE NO PICTURES because of licensing issues. The print edition has lots of pictures, but many of the crime-scene photo's are censored.

Output: Positive


Input: Consider Input: I received a different adapter so I cannot really tell you about the Macally adapter. I received an adapter from Inspire and it does not have the longer cord, the velcro strap or the led lights. But it does charge my computer and it arrived quickly.


Output: Negative
