The Ion Mug is AWESOME! It keeps coffee warm, even steaming if you want! When the coffee pot has the last cup and its cooled down, just pour it into you Ion Mug and it heats up to steaming. Careful with creams and additives when it gets to a small amount in the bottom it will cook it into a solid. But, that's my fault because I set the cup down and went to do something. I thought I ruined the cup but the teflon coating bounced it right back to like new. I will only use it for black from now on but LOVE it in the garage or outside on the porch in the cold. The handle is sleek and it's lightweight. I would hope to have more pamphlet info of other examples to get ideas and more infor on how to make sure it's off. Is it a fire danger at all if the cup accidentally gets turned on inside the cupboard? My only concern. Thank you Ion Mug! I already have friend that want one! Do you do cooling ones for wine?
