Given the task definition and input, reply with output. In this task, you're given reviews from Amazon's products. Your task is to generate the Summary of the review.

The break on our first stroller broke after 3 weeks use. Amazon very efficiently sent a replacement which had the same problem after just two weeks. Clearly there is an issue with the breaks on this stroller. Avoid buying it - a stroller without a break is dangerous.
