## Customer feedback

Aggregate ratings lean positive, with many five-star ratings, but a smaller share are two-star. Without review details, the ratings cannot establish what customers liked or disliked. They also do not confirm the listed capacity, lock, or water resistance, which buyers should assess against their storage needs.
