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.
It does its core task extremely well - it keeps my coffee hot for a very long time. It's also attractive, well priced, and convenient for 1 handed use. It would have been 5 stars if not for 2 annoyances. The pouring/drinking lip feels unpleasant compared to my other thermos travel mugs, so I don't enjoy drinking from it. It's also a little thinner, and this makes it a loose fit in my car cup holder. However, I will keep using it because I get to have hot coffee many hours later than I can with any of my other travel mugs. I now know I can still enjoy my coffee at lunchtime if I get too busy to have it earlier. On long car trips, I know I can take 2 coffees!
