Q: In this task, you're given reviews from Amazon's products. Your task is to generate the Summary of the review.
Quality of the shell seem good. Reason for two stars: - Buttons are too stiff, pressing any of the buttons require a lot of force and makes me question the durability of it. - Trunk and remote start buttons did not work at all. - Returned it, still using my original one.
A:
Trunk and remote start buttons did not work at all!
