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.
Never thought the lid is so hard to wash. I have to wash 6 x parts of the lid after use and this should be dried well, otherwise water drops onto my face when I drink out of the hole. It is very nice looking and coffee seems stay warm for long but I will never buy again. Very disappointed.
