PROBLEM: Review: This cell phone holder is one of the poorest in quality I have ever seen. The Velcro or Hook and loop come un-sewn leaving your cell phone free to fall to the ground. I wouldn't recommend McGuire-Nicholas products to anyone. Their products are some of the poorest made products on the market. 
 Polarity: Negative

SOLUTION: True

PROBLEM: Review: I stongly dislike this book. There is too much meaninglessness to it. I can read seven pages for something that can be stated in one paragraph...it's awful. Only Webster would be able to read this and not use a dictionary. I have understood two chapters! I don't see why an English teacher would like this book because it is full of empty sentences! It is hard for one to read this book without his mind wandering. As I stated before, this is not my kind of book! 
 Polarity: Negative

SOLUTION:
True
