“This well-designed mug keeps my drink hot for a long time without burning my hands. I love the design and the matte look. I'm a fan of the Waterdrop metal drinking containers and highly recommend them. Just be careful to keep them in a bag when you're carrying them from place to place because, if you're like me, you'll drop them and they'll get bashed up. The good news is that even if that happens, you can still use them, unlike most plastic drinking containers.”
