Solution: Negative
Explanation: Review writer does not like the book because it was boring, therefore it is a negative review.

Problem: Though I've had this only about a month, it is starting to go. It puts shards of sharp plastic in the food. (From searching the net on this, I find that my experience is not unique, either.)Do NOT buy.Other better brands include Unicorn (recommended by a famous cooking magazine), Peugeot, Firth, and William Bounds.

Negative
