Bests & Worsts Reviews from Amazon

This mug is shortlisted as one of my Favorite Things, right after my dog. It's so nice to make a cup of coffee and then get busy doing something else, and when I come back to it my coffee's still a perfect 140°, right where I left it. Also of great importance, I was an early backer on their crowdfunding campaign, and when one of their early prototypes failed, they couldn't have been quicker to replace it. Great people! Highly recommend!
