PROBLEM: the filter works well to trap most of the odors for a good price and is easy to clean. I would recommend it

SOLUTION: Good Review

PROBLEM: My son was very upset when the book didn't have pages. I called and received a new book, which also wasn't the correct book. Needless to say it will go in the garbage. What a rip off! They should take out all reviews that are not written by "Amazon Verified Purchase". This has never happened before.

SOLUTION: Bad review

PROBLEM: My friend and I decided to rent this video for $10. The description on here makes it sound really scary. We just rented it. It was horrible. The actors were all bad. Some of them where in high school while others couldn't be more than 15 or 16 at the time they were doing this. After about 10 minutes, we almost shut it. About 5 minutes in, though, it started getting good. Then suddenly there were these long boring scenes. This is so not scary even though it's rated PG-13.

SOLUTION:
Bad review
