In this task, you're given reviews from Amazon's products. Your task is to generate the Summary of the review.
One 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!
Solution is here: Cat hates them
Explanation: It's a correct summary because the owner's cat hated the product.

Now, solve this: It could not go over transitions between rooms and constantly got stuck. It could not figure out how to get to the next room. I returned this and the customer service was good and refunded my money.
Solution:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
