• The Ember Mug is designed to maintain already hot liquid. For best use, we recommend pouring in liquids that are hotter than your set temperature! If cool or cold liquid is poured into the mug, it may detect as empty and not heat.

• It will heat up cold coffee but you will need to stir it periodically so it can be frustrating. I found if you don't then it will think it's empty and has 0 fluid in it
