Problem: I've read this book with much expectation, it was very boring all through out the book
Solution: Negative
Explanation: Review writer does not like the book because it was boring, therefore it is a negative review.

Problem: One of my 4 Neoprene seat covers got ripped by a vacuum cleaner after just 1 year, something that should not happen to begin with. But Coverking customer service is not helping and would not sell just the replacement seat cover, has to sell 2 at a time, at full retail. Beware of their durability and quality control, and definitely beware of the customer service, or lack thereof.
Solution:
Negative
