Very effective at keeping drinks hot! Nice design, easy to drink from, no spilling. Lid is easy to clean and can be put in dishwasher though mug is hand-wash only.
I have at least 6 Contigo Autoseal mugs and they are the only ones that I use. I have had 2 problems with 2 different mugs that the warranty quickly resolved. [This review was collected as part of a promotion.]
I didn’t receive this item yet... I have been waiting for almost two weeks .. and I called the customer services but no body answers ... it is wasting time .
