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 analyzes reviews to verify trustworthiness.
I bought this for my husband for his birthday, he's not really into tumblers but this one has him hooked! It's easy to clean, keeps his coffee warm for hours while he's out snow plowing!!! He doesn't leave home without it now! Perfect gift for him, especially with his love of the Cleveland Browns!!!
