Definition: In this task, you're given reviews from Amazon's products. Your task is to generate the Summary of the review.
Input: Title says everything. It's 2 x 2lb bags. Total 64oz. The $x/oz price is based on 8lbs but you actually get 4lbs. What makes it a black hole is it is not returnable. Worst experience on Amazon!

Caution: miss leading title, wrong $x/oz price, and not returnable. Total 4lbs not 8lbs
