Ember Temperature Control 10-oz Smart Mug

This self-warming coffee mug functions even without the app and automatically recalls your last-used temperature (135°F initially). It comes with an LED light located at the base that will indicate when your beverage is heating up, cooling down, ready to drink, or in need of charging. The price drops from $149.99 to $71.99.
