What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Reliably holds a user-set temperature within a narrow range, eliminating the need to rush through a drink
- Stainless steel body with ceramic coating feels solid and premium; bottom-heavy design resists tipping
- Automatic wake and sleep behaviour — activates when hot liquid is poured in, sleeps when empty — works seamlessly
Reviewers push back
- Battery life off the coaster is short, around 80–90 minutes when new, and degrades noticeably with heavy daily use over time
- Temperature adjustment requires a smartphone app; no physical controls on the mug itself
- Inner ceramic coating can scratch and wear if a metal spoon is used, revealing the substrate beneath
Reviewers broadly agree the Ember Mug 2 delivers on its core promise of holding a precise drinking temperature, with strong build quality and a well-designed app, though limited battery life and mandatory app setup are consistent complaints.
