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.
I just love this water bottle. Perfect size for my uni bag, keeps water very cold for a long time and the colour means it'll stand out in a crowd. Magnet feature - you think is a little gimmicky until you go back to a water bottle that has its lid just flapping in the breeze and then you realise what a nice little addition it is. highly recommend.
