    10oz is not an optimized size.

    Wish to have bought the 14oz. 10oz is just too small.

    Doesn’t work as well as I had hoped. I drink tea every morning and this cup helps keep it warm for awhile, especially the bottom part near the heating unit. So to top 1/2 is cooled off and the bottom 1/2 is warm. So I guess if I stir it frequently it would help. But I’m a little disappointed in it.

    No, I would not recommend this to a friend

      Hi Teadrinker, thank you so much for writing a review! The heaters are located towards the bottom of the mug, so lower liquids can get hotter but we do recommend stirring your drink occasionally to ensure the mug can heat evenly. We do appreciate your feedback and will pass this along to our team as we continue to improve! Ember
