Example Input: I had bought this and one other book at the same time to try out on my 2 1/2 year old. She is in preschool right now but she will have the first lesson of these books read by another person then repeated back to her. The instructions are fine for her but it does not seem practical that only a few times can be done with two people, or else they would say several things without saying anything!! So we never do it.
Example Output: Bad review

Example Input: After the first month I bought this product It fell from a desk and broke. The plastic used is cheap. Do not buy this!
Example Output:
Bad review
