Negative Positive
Title: looks good, bad design
Review: This mug does not keep coffee hot at all!The outside of the mug gets very hot when you put hot coffee in it indicating poor insulation.It seems as if the outer wall is actually touching the inner wall of the mug or that the insulation between the two layers does not work well.I am very disappointed in this mug since it was advertised as "Double Wall" implying it had good insulation.
