    Keeps beverage warm, but coating flakes off bottom and Bluetooth app never can complete an update (if there is one - never could tell for sure).

    Not my kind of cup, just didn't work for me, it was keeping my coffee hot only when it was hot lol, when the coffee was cooling down, I have to re-charge it, and if the drink is cold, warm it in there will take all the battery again.

      Hi EXAMINADOR, thanks for leaving a review and sharing this! The Ember is designed to stabilize an already hot drink down to your set temp and not heat one up, so for best results, we do recommend pouring in hotter than your set temp (around 165°F and above). With that said, we appreciate your feedback and will pass this along to our team as we continue to improve! Ember
