Report an issue with this product or seller
I’ve been using the Ember Smart Mug 2 almost every day for about a year (I skip caffeine on Saturdays), and it’s easily one of my favorite purchases. I haven’t had a single issue with it during that time.
What I like:
Keeps my coffee at an exact, consistent temperature once set
The app lets you dial in your preferred temperature, and the mug remembers it afterward
Build quality feels premium, and the copper finish looks great on my desk
Works especially well when paired with a sliding lid to extend battery life
With the lid, I rarely need to use the charging coaster while drinking
What could be better:
The app can be a bit annoying to use, especially during initial setup
Battery life is short without a lid, so slow sippers will want the charging plate within reach
Once everything is set up, the app becomes mostly hands-off, and the mug just does its job. If you like your coffee or tea at a precise temperature and tend to sip slowly, this mug—especially with a lid—has been a daily essential for me.

Customers say
Customers find the mug keeps coffee hot and consider it a fantastic product. However, the battery life is poor, lasting only an hour, and the ceramic coating peels off over time. Moreover, the mug is expensive for its quality, and customers report issues with Bluetooth connectivity, refusing to pair and stay connected with the app. Additionally, the mug's reliability is mixed, with some saying it works well while others find it unreliable, and ease of use is also mixed, with some finding it easy to use while others report issues with the brass pins getting stuck in the base.
