This Mug is Smart

Although it looks a typical mug, the Ember Ceramic Smart Coffee Mug is a beverage marvel with a connected coaster that links to an app on smartphones or smartwatches. The app can be used to keep brews at perfect temperatures, provide instant alerts when desired temperatures are reached, remotely adjust temperatures to perfection, switch between Celsius and Fahrenheit for ultimate precision, and save pre-sets for favourite drinks. This intelligent mug holds a full ten ounces, perfect for tea and coffee just as you like it.
