To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Really great quality, as the thermos brand is. This design is nowhere near me in stores. It’s great that you can purchase replacement straws for when they inevitably break. So easy to clean and my son loves it.
