Title: Pour insulation
Review: I have used this mug for over a month now, so far the autoseal works well and it is an excellent feature, the lid is cleaned to a satisfactory level by putting in the dishwasher at least once a week, my only problem is with the insulation, I pour my coffee at 8:00 when I start work, and I wanted a mug that keep it hot till lunch at noon, however I am disappointed with this product because by noon it's already cold or little warm at best, but for sure not hot enough.
