Smug Mug can keep your beverage warm from the first sip to the last drop! Covered with a layer of thermal conductive glass, it effectively transfers heat to stainless steel, ceramic, and glass mugs. The wipe-clean, water-resistant design is lightweight, sleek, and comes in 5 fashion-forward colors. It uses smart technology to keep your beverage at the temperature you choose. It also has a timing feature that allows up to 9 hours of keeping your Mug warm. The gravity induction sensor technology recognizes the weight of the Mug will go into a standby mode when it is low or empty before turning off after 5 minutes. Finally, the Smug Mug’s dual temperature settings allow you to choose from two desired temperatures.
