Definition: In this task, you're given reviews from Amazon's products. Your task is to generate the Summary of the review.
Input: Do not buy! The quality of the item is very poor, I should have listened to previous reviewers. 2 of these lights stopped working almost immediately. Today is exactly 5 months after these lights were bought and none of them works. I have different solar lights in the same location as these and they work fine, so the problem is not in the lack of the sun during the day.

Bad quality, all of them stopped working in less than 5 months
