question:
Bought this for my 5 year old Justice Leaguer. My son is not a rough player but we went through 4 (YES, FOUR) of them before we finally got one where the elevator didn't break in the 1st 2 weeks. Mattel needs to get their act together and design toys that have durability. VERY disappointing!
answer:
Negative


question:
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.
answer:

Negative
