Customers are saying

Customers highly value the product's exceptional temperature control, which is frequently highlighted as its most impressive feature.

    It seemed nicer than it was. I like that my coffee stays hot longer but that’s about all I’m getting out of it. Battery dies very quickly for my tastes. End of the day it didn’t end up as practical as I had hoped.

    This mug is great and at an unbeatable price ($99 when I purchased it on sale)! Great Gift for the holidays and everyone enjoyed it. I do want to see how long it will last, the coating seems to have trouble according to other reviews, so be on a lookout for that nonetheless.
