Given the task definition, example input & output, solve the new input case.
In this task, you're given reviews from Amazon's products. Your task is to generate the Summary of the review.
Example: My cat won't touch these. My dog, however, chews them and makes a mess all over the carpet and I can't get the shredded sticks out! Messy. Waste of money!
Output: Cat hates them
It's a correct summary because the owner's cat hated the product.

New input case for you: Very disappointed with the quality of this product. The unit I received cannot be assembled per the instructions because the bolt is too short (as noted in other reviews). Makes me wonder if the manufacturer ever tried to assemble one before selling it on Amazon.
Output:
Very disappointed with the quality of this product
