Yeah, I can't conceptualize how this mug is supposed to work especially at the speed it claims. It seems like it would just muddle the temperature down to mildly above room temperature over multiple minutes. So that the drink and material are the same temperature but the material holds heat due to being insulated on one side. What this would mean is the mug would get less effective as you drink more. The insulated mug would make the time longer but it is no where near something like the Ember that converts electricity to heat. Seems like KS schlock for people that don't want to think about if / how it works.
