Here is a smart mug that lets you enjoy your coffee and other hot drinks at the right temperature. Ember keeps your coffee at the right temperature for up to two hours. Just turn the dial at the bottom of the mug to adjust the temperature. You also have the option to do it on your smartphone. In fact, you can save drink preferences for the future.
Ember is made of BPA free materials. It has a stainless steel inner vessel and space-grade thermal insulation. The mug is leak-proof and waterproof. It holds up to 12oz of liquid. Yet another interesting Indiegogo project.
