    I love these mugs. I have three now - one for my home, office and to travel with. I do wish the length of time keeping the drinks warm before needing to charge was longer. It lasts about an hour, do if I get busy or distracted, I have to reheat the drink. Other than that, I am enjoying them.

    Great mug, was a gift and my family member loves it. Great for Coffee or even hot soup. Only downside is that the battery charge really should last longer.
